Well here's one everyone can enjoy without feeling guilty or breaching copyright. Vertex Access developed a prototype shaft inspection system along similar lines - this model used guide wires and a custom winch to prevent excessive rotation and speed variation, but even then it's not perfect - though at 60 metres depth it's not that bad either.
It shot video straight down, and rotated automatically to take stills images, so a panorama of the entire shaft could be 'unwrapped' later. It also had gas monitors installed, and thankfully prevented an abseil into a gas-filled shaft on one occasion while looking for a dead cow. We found it, jammed in the shaft at a constriction about 35m down.
I helped them set this video shoot up, and a few others besides - it's at Whalf (Hillocks) Mine in Monyash. We even got permission in writing from the National Trust, who generally like this sort of thing - if they're asked nicely. The first few seconds are a speeded-up view to the bottom, and then it's real-time back up to the top, so plenty of time to study the geology and mining modifications, including the abandoned 'double shaft' in the top half. And it's not full of water either.
I also got to practice my animal communication skills whilst it was ascending, coordinating a re-shoot of the 'Atom Heart Mother' album cover ;)
