As quite a number of fans of the show appear to like Ben's miniature pinball tables, I thought some may be interested in the idea of a miniature 9pin bowling table.
I recently spotted one having been constructed using the Fischertechnik construction set:

There is a bit more info on the build here (page 28 - 31) but unfortunately I can't really read it as the article is in German, but the pictures look quite good

It looks like it uses an old friend of Ben's from the camera tracking project, the PixyCam.
The design appears to have been based upon a project featured way back in a 1979 club magazine (page 5):

which is quite amazing if you consider the technology available to hobbyists at the time.
Anyway, I thought that it may make for an interesting show project. How could it be improved ?
