Smart Atomix

Like Smart Brix, but it's atoms now. Each atom module is a unit that when it connects to other atoms it knows. With that knowledge, it tells you what molecule it can or can't make. Molecules would be able to do the same, giving you a living science experiment modelling toy. Much computing required per atom/molecule, but we're likely pretty close. It just means each unit is self-aware. Perhaps the atoms must be on an aware pad of some sort that knows which atoms are where and how they connect and that feeds to a computer to off-shore the computing power. That way each atom doesn't need to be fitted with a full chipset.
