Draw, trace, play games and more with the Discovery Art Projector. Project on walls and ceilings up to 20 times the original size. Create Your Own Layerable Artwork: Use multiple discs to layer artwork and achieve a unique look! Try drawing related designs on multiple discs, such as a background on one disc and animals or people on other discs. Then stack them on top of the lamp to see how they blend together into one special drawing!
