Hi my name is Johanna Tano 
and we’re in Stockholm in my atelier.
I work as a new media artist.
I am actually a programmer but I use 
different kind of software and hardware  
and try to combine them in 
experimental or new ways. 
So there’s a Raspberry Pi 
connected to each TV. 
Its lika a small, quite cheap, computer
 and they are all connected to 
the network that I’m also connected to.
Now I’m running a server on my computer 
and you can see when I start it
that all the different TV’s instantly 
connecting to my computer here.
This is a system that I built 
for mapping up.
They all share the same source image 
but then I have a system for setting 
exactly the X and Y offset for each TV
so you can map up really precisely. 
They’re all connected to my server 
but there is no content streaming.
I need to send an image or a video 
or a live camera feed or something.
The system I’m using to send the actual 
image from my computer to the TV’s
is a program called Syphon.
That’s something you can use 
if you’re on a Mac computer
and what it does is that it can 
share images on the network.
And there’s a client inside 
each of these raspberry Pi’s
that then receives, through 
the network, this image.
But the whole system with 
the mapping and the setup
 and the structure and everything, 
this is something that I’ve built 
on my own.
Most of the times you just try
and I mean it’s nothing dangerous
so you just try to figure out 
a way how to do something.
Then it works and 
you have to figure out how to use it.
