Build some bright ideas with this ingenious, illuminated set of interlocking construction blocks. Just add blocks to the base (battery or usb powered), and each one lights up when connected! Compatible with other construction block systems of the same size, this set of 36 or 102 blocks will inspire endless creativity in kids and grown-up geeks alike. It makes amazing sculptures of geometric light, in four modes (always on, 15 min. auto-off, flashing, and fading). Build your own custom nightlight, skyscraper, glowing robot, or anything that lights up your imagination. Made in China.
