We love Kickstarter projects here at GRM. The latest great project that we have stumbled upon is Blockets.
Blocklets are a system of interlocking pieces that can be used to make anything, from sculpture to furniture, and soon Arduino-based robots. Made of laser-cut wood and acrylic, they snap together with a satisfying 'click' and they feel great in your hand.
A $25 pledge will get you a basic Blockets kit with 86 wood and acrylic pieces.
