littleBits are tiny circuitboards that you can stick together with magnets to make little electronic machines.

Just as Legos allow you to create complex structures with very little engineering knowledge, littleBits are simple, intuitive, space-sensitive blocks that make prototyping with sophisticated electronics a matter of snapping small magnets together. With a growing number of available modules, littleBits aims to move electronics from late stages of the design process to its earliest ones, and from the hands of experts, to those of artists, makers and designers.

A bit like Siftables.

From the recent TED conference, a demo of Siftables, blocks that are smart. What I find most interesting about Siftables is that the blocks form a computer that doesn't need instructions but it doesn't seem like a computer at all, i.e. the Holy Grail of computing. (via peterme)
