Small is beautiful. The gadget, to make it interesting, does not have to be big and flashy. And how else does it carry an important message? It's no longer a gadget. It's a treasure! Some prefer a fridge magnet, others prefer keychain. It's important to hit your tastes and tastes. Sometimes, such trifles, if they are a podarki, become more important than a million dollars.
Remember that it is also worth making yourself gifts so to work!
