Researchers at MIT invented a chameleon-like "reprogrammable ink" that allows you to "paint" colors onto a surface using a projector and UV light.

This is the fifth or sixth chameleon paint job completed at Efrain and Mary Ramos' Floreciente neighborhood garage. ``It's getting more popular, especially on older cars,'' Mr. Ramos said.

A new 3D-printing ink, inspired by the color-shifting capabilities of chameleons, has been developed by scientists, offering the ability to change colors within a single print job.
