You've added a laser to your phone - now add lasers to your building blocks

Laser Pegs are similar to a lot of toy building blocks on the market, but you build lighted creations with these blocks.  Each kit has 72 blocks, and each block has an LED light and low-voltage circuitry; the power supply in the base makes your creations glow with light.  There are a variety of kits that range in price from about $13 to $50.  You can build robots, little Hot Wheels-type cars or fancy drag-racers, or air craft.  There are even licensed MLB and NFL kits.  You can build the featured toy and several other designs with the included blocks.
