I made it as a bit of a giggle, but it ended up kinda cool. I might re-rig it to handle heavier cinema primes, but it works nicely with small and loose lenses.

Its a fully functioning wireless remote follow focus, with numeric and visual display, digital mark points and automatic transitioning between marks... Made entirely out of Lego. hehe. no seriously. (Except for the rail mount and lens gear)
