Reuse your old Compact Disks and convert them into beautiful modular arrays; storage, lighting, decorative, racking systems + more. CDBITS are small, yet robust 'bits' that connect to used or new Compact Disks and DVD's, converting them into expandable modular arrays. Racking/storage systems, lighting displays, decorative features and even sculptures. Re-purpose your old unused DVD's or CD's into something usable. Blank media disks retail for about 3-4 cents each and can be purchased from most electrical/computer outlets including most supermarkets - making them one of the cheapest, readily available building blocks money can buy. Forget lego, use CDBITS! Find the assembly and testing video here: http://youtu.be/r_36osG8QdQ
