The Barbie Digital Dress Doll lights up the runway with her customizable dress, made of a touch panel with 114 tri-color LEDs. Using a stylus, kids can design different animated light patterns. She comes with pre-programmed graphics, and her dress also has a party mode that will animate in response to sounds. This Barbie shines in stores this August for $50.
