the present inventive subject matter provides for a transformative floor mat with interlocking panels and play pieces , which can be used to form floor mats , stacks of tiles , and play figures . in fig1 , a transformative floor mat 100 generally comprises a first panel 110 , a second panel 160 , and various play pieces 170 , 180 , and 190 . first panel 110 is configured to mate planarly with second panel 160 via connecting edge 112 on first panel 110 and connecting edge 162 on second panel 160 . connecting edge 112 comprises a series of interlocking structures , trapezoidal recesses and 114 and trapezoidal projections 116 , which match trapezoidal recesses 164 and trapezoidal projections 166 composing connecting edge 162 . trapezoidal projections 116 are preferably slightly rounded to minimize any sharp edges in transformative floor mat 100 . while connecting edge 112 is shaped to have trapezoidal projections and recesses , the connecting edge could be shaped in any suitable manner to interconnect the panels . preferably , the projections and recesses are shaped with a wide tip and a narrow neck to prevent the panel from easily slipping out of the mating interlock . as shown , the entire perimeter of first panel 110 comprises interlocking structures , allowing first panel 110 to interlock with another panel in any direction . however , it is contemplated that a panel could be constructed with at least one edge without any interlocking structure . first and second panels 110 , 160 could be made from any suitable material or mixture of materials commonly known for floor covering , including rubber , foam , wood , or other elastic materials . in preferred embodiments , the panels are made from a co - polymeric foam , for example polyurethane . more preferably , the panels are made from ethylene vinyl acetate (“ eva ”). the surface of panels is slightly corrugated to provide a textured surface that prevents a user from slipping on the panel when used as a floor mat , although flat surfaces and slightly curved surfaces are also contemplated . second panel 160 is constructed similarly to first panel 110 , but second panel 160 also has play pieces 170 , 180 , and 190 , which are all configured to mate planarly in matching through holes . while these play pieces are preferably created by “ stamping ” or otherwise cutting holes in second panel 160 , play pieces 170 , 180 , and 190 could conceivably be molded separately from second panel 160 . play pieces 170 , 180 , and 190 could also be configured to mate planarly within non - penetrating holes in panel 160 to provide for thinner play pieces . the edges of the play pieces are preferably slightly corrugated to provide additional friction to hold the play pieces in place within second panel 160 . preferably the friction force between the play pieces and the panel is just enough such that a child could easily separate the play pieces from the panel . play pieces 170 , 180 , and 190 have interlocking edges 172 , 182 / 184 , and 192 , respectively . these interlocking edges are configured to mate planarly with the holes formed in second panel 160 such that the play pieces mate with second panel 160 form a substantially contiguous plane . as shown in fig2 , these interlocking edges are also configured to mate angularly with one another to form alligator play fig2 . while the interlocking edges are configured to mate angularly at a substantially 90 degree angle , the interlocking edges could be configured to mate at different angles , or at a variety of angles , without departing from the scope of the invention . since the recess along interlocking edge 182 is configured to receive the width of body 170 and the recess along interlocking edge 192 is configured to receive the width of leg 180 , it is preferred that the recesses along the interlocking edges are slightly smaller than the thickness of the play pieces . this allows a tighter fit between play pieces when they are connected , and assists in preventing a play figure from falling apart absent a significant force applied by a user . fig3 - 7 , fig8 - 11 , fig1 - 15 show other preferred embodiments of transformative floor mats configured to interlock to form a variety of animal figures . fig3 - 7 depict an alternative transformative floor mat 300 with panels 310 , 320 , 330 , 340 , 350 , and 360 . the edges of panels 310 , 320 , 330 , 340 , 350 , and 360 are not configured to mate planarly with one another , and can therefore slide away from one another easily . within the panels of floor mat 300 are collectively cut several play pieces — central body pieces 332 , 342 , 352 , and 354 , side body pieces 312 and 324 , leg pieces 344 and 364 , tusk piece 334 , and head piece 362 . the play pieces are all configured to form elephant play fig5 . central body piece 332 comprises eyes 333 , which are preferably a different color than the rest of central body piece 332 . this differential color shading could be achieved in any suitable manner , for example by dying the surface of the play piece an alternate color , or by providing punch - out eyes which could be replaced by play piece eyes of different colors . in this manner , a user could customize a color palate of elephant play fig4 with separate and different color parts to replace the corresponding parts , such as eyes 333 , inner ears 363 , toenails 365 , and nose 356 . as shown in fig4 , central body pieces 332 , 342 , 352 , and 354 all have connecting edges with interlocking structure along a portion of their perimeter to form central body section 400 . central body section 400 is flanked on two opposing sides by side body pieces 312 and 324 , which are all configured to be received by leg pieces 344 and 364 . by flanking body pieces around the central body piece , the body of elephant play fig5 is strengthened and stabilized . elephant play fig5 also comprises tusk piece 334 , which angularly mates with recess 355 . as shown , even curved play pieces could be configured to angularly mate with play pieces . fig8 - 11 depict an alternative transformative floor mat 800 with panels 810 , 820 , 830 , 840 , and 850 . the panels comprise central body pieces 812 , 822 , and 824 , side body pieces 832 , front leg 814 , rear leg 826 , front feet 836 , rear feet 838 , and head pieces 834 , 842 , and 852 . the play pieces are all configured to form lion play fig9 . as shown , front leg 814 and rear leg 826 are both configured to mate with side body pieces 832 at a substantially 90 degree angle from the bottom surface of the side body pieces . however , because side body piece 832 has a curved angle , front leg 824 and rear leg 826 are not parallel with one another . this allows lion play fig9 to have an angled stance . likewise , front feet 826 have recess holes that run straight up and down to match front leg 824 , while rear feet 838 have recess holes that are angled , to accommodate angled rear leg 826 . central body piece 812 has an open tiered recess 813 which allows the recess to receive head piece 834 on a separate level to head pieces 842 and 852 . open tiered recess 813 contrasts with closed tiered recess 815 , which has a narrow opening that fans out to a wider opening , which then splits into two tips . closed tiered recess 815 provides for a tighter fit when front leg 814 receives central body piece 812 and side body pieces 832 . closed tiered recesses are especially preferred for body pieces that could be roughly handled by a user . fig1 depicts an alternate transformative floor mat 1200 with panels 1210 , 1220 , 1230 , 1240 , 1250 , and 1260 . this transformative floor mat has a plurality of play pieces that are configured to form a plurality of different car play fig1 , 1320 , 1330 , and 1340 , shown in fig1 a - 13d . axle 1312 is a play piece that sits separate and apart from the panels , and is only used to help spin wheels 1222 . axle 1312 could be made from the same material as the play pieces , but is preferably made from wood or plastic to assist allowing the wheels to spin . while axle 1312 is not configured to mate planarly with transformative floor mat 1200 , axle 1312 could be configured to mate with a recess in one or more of the panels of transformative floor mat 1200 without departing from the scope of the current invention . as shown , the play pieces are configured to mate with one another in a variety of different ways . for example , car play fig1 has a different car cabin hood 1232 than the car cabin hood 1234 that car play fig1 uses , car play fig1 has attached spoiler wing 1212 in a different configuration than car play fig1 , and car play fig1 has attached a different number of wheels 1222 to axle 1312 than car fig1 . other car configurations are possible than what is depicted in the drawings . one of skill in the art would be able to use transformative floor mat 1200 as a car building kit to build a plurality of other car play figures that look different from one another . fig1 -
