I'm a 28 years old guy. I got Legos for christmas. And you know what? I absolutely love it. But how to have twice as much fun with a little set of Legos? Try knolling.
With my shaky hands it took me an hour to get those organized. And then it turned out it's not that easy to get the light right. These little shiny blocks reflect everything. I'm not entirely happy with the end result, but hey, at least I have Legos now.
