Ultraviolet Glow in the Dark Drawing Pad 15-5/8" x 11-3/4" Ultraviolet Art Ultraviolet Art could be a glow-in-the-dark guy named Garfunkel, or it could be this nifty set that lets you use an LED-powered UV pen to draw on a 15-5/8" x 11-3/4" reactive pad to create GITD art. The farther away you move the pen, the wider the line. Includes alphanumeric and some basic cartoony stencils. (Ignore the "invisible ink" end of the pen, its death made it surplus, but the fun part works great.) The art, of course, is transient, but then what isn&#39;t?
