[Crazy Dazz]

I'm looking for something to “do” with my 13yr old son, something in the way of a project. Something we can “build” for want of a better idea.
This is not just about spending time (we do that) but trying to get him interested in something besides video games. He is an exceptionally smart kid, tested off the scales in math and reading. Does ok at school but is easily bored and has the attention span of a goldfish. He shows some interest in “how things work” but not to the extent of being particularly interested in cars.

I’d like it to be something that will progress over time, and also something practical. It’s got to be something that stimulates his mind and piques his interest. Simply helping me assemble something of my choosing is pointless.

As you can tell, I have no idea, which is why I am asking.
