I don't own either of these, but I've noticed there's a couple brands of these magnetic building sets. http://magnetixtoyreal.info/magnetix-micro-magnetic-building-set/
There's Magnatiles and geomag on this page

I got the boy a small trio set for his second birthday but he wasn't strong enough to use it 'till he was 2.5. He's 4. We've added to the set. He still plays with the Trio all the time.

A game he loved was Perfection, but without the timer. http://www.amazon.com/gp/aw/d/B004NAJI1K/ref=redir_mdp_mobile

Here's his latest original Trio designs a dog, a trophy, and a caterpillar. The caterpillar looks suspiciously like a weightlifting bar, a quid ditch broom, a walking stick and several other designs I've seen. Trio has a satisfying snap.
