WB 10x10 Blind by Graham Siggins

Completly insane!
Graham Siggins solved blindfolded a 10x10 cube in 54:43.77 minutes

28.50 min. for inspection and memorization, and 25.53 for execution. The real achievement is to make no mistakes.

When I see this, I wonder one thing: How many movements does he need to memorize?
