That looks pretty cool. My favourite home/office made finger toys are when you take 2 of the little plastic protectors off of the ports of screencards (and/or cables). They're a great size to stick your fingers a bit into and they usually fit inside each other nicely (it's ok if they're loose, but really great if they stick nicely). They're pretty durable too, unless if you play too hard they can last a very long time.
