The host of this video vacillates between amusingly self-deprecating and annoyingly self-aware but, despite that, this short video on the 3DS-EXP 645 Film Camera is worth a watch. It's a six lens camera designed for making lenticular prints, aka those prints that "move" depending on what angle you view them from. Almost every mention of this camera online is actually a link back to this video - a redundantly circular trip which just seems to confirm how rare this camera actually is. Occasionally you can find full product images, so it's worth digging around to find out even more after viewing the above.
