Launching soon on Kickstarter, sign up now- BRIXO blocks are chrome-coated building blocks that act as electric conductors. They interlock to produce complete simple circuits with no wires involved, adding lights, motion and sound to any construction. The blocks are powered by a low voltage built-in battery and coated in chrome, a non-toxic metal, to ensure your safety. BRIXO include LED lights, motor blocks and even sound, light and proximity sensors. And all are fully compatible with standard building blocks.
