If you stare long enough at Hans Kotter's bright and colorful sculptures, you'll know how Alice in Wonderland felt when she stared down the rabbit hole.
To hypnotize his audience, the German artist uses color-changing LED lights that are strategically positioned inside Plexiglas. The lights are controlled with a remote control and the walls are mirrored inside. When viewed at the perfect angle, a deep tunnel appears. From other angles, you'll only see an interesting array of light and color.
This piece, titled Tunnel View, was showcased at the 2011 Kinetica Art Fair in London.
