Illustrate a whimsical cyberpunk gnome, a fusion of fantasy and futuristic elements, standing amidst a bustling, neon-lit cityscape. The gnome, clad in a sleek, form-fitting bodysuit adorned with intricate circuit patterns and glowing LED lights, exudes a mischievous charm. Their pointed hat, reminiscent of classic gnome attire, is updated with high-tech enhancements and augmented reality visors that overlay digital information in their field of vision. The gnome's beard, braided with fiber optic strands that shimmer in a rainbow of colors, adds a unique flair to their appearance. They carry a miniature, holographic interface device, manipulating virtual objects with precision and skill. In the background, towering skyscrapers shimmer with holographic advertisements and bustling hover vehicles zip through the air, creating a vibrant, dynamic backdrop for this modern gnome's adventures.
