Turntable Scanner
I thought I'd better document an idea that I saw in O'Reily's "Make" blog while looking at postings about RepRap - I'm unable to find the original link. The concept was to use a rotating turntable and a moving laser pointer in conjunction with a video camera and some clever software to scan in and digitise an object.
Well, the Meccano turntable would both rotate and lower the object simultaneously so a static laser pointer could be used. As the method was already proved, it would appear that RepRap + laser pointer + video camera = 3D scanner.
Unfortunately I'm a bit busy making the fabricating side of things, but if anyone wishes to make a turntable-based scanner do let me know how you get on!

No, not that one. This moved a laser pointer dot rather than spreading the laser into a line.
But whatever works is good!
