The other day I bought a refurbished Dell Studio Hybrid, a cute little desktop computer called a “hybrid” because inside it has as much in common with a laptop as with a mini-tower. I’ve never bought a Dell before, but its nine-inch form factor and attractive chassis along with the refurbished price gave it a lot of appeal as a replacement for my hulking living room machine.

It has a lot of nice design touches,  most of which I saw in the many photos online, but there’s one that I didn’t notice until I started playing with it, unwisely turning it this way and that while it was running. Well, I won’t spoil it for you—check out the video above (there’s no audio).
