I'll attempt to solve a 105x105x105 cube over the course of a few weeks. I'm confident that it'll be done within roughly 200 ~ 250 hours of solve time. I'll be live feeding my attempt, as well as recording via hypercam to upload a time-lapse. Hopefully, this will set a record for largest cube ever solved by hand. The current largest cube ever solved by hand I'm aware of is 100x100x100.
