Ambient Glow Technology's Glow Stones combine with concrete--they either mix in freestyle or nestle in methodically--to create everything from illuminated pathways to Fairyland to sculpted lawn ornaments to mood-setting bathroom vanities. Glow Stones appear bone white in normal lighting, when they're soaking up luminous juice for their show, and then blaze in a choice of Aqua Blue, Sky Blue, or Safety Yellow when darkness falls. Stone sizes range from 1/8" to 3/4", and cost $54 per pound. One pound of the 1/4" glowing booty will cover an area of approximately 28 square feet if stones are set every 3" to 4".
Those not in the mood for F'ing around with concrete and pebbles can awash surfaces that need a little UV radiance in Glow-in-the-Dark Graffiti instead.
