Very, very cool! I really don't know what else to say, except this seems like something that you would make. XD
3 Minutes.... The quickest I've ever been able to solve it, normally takes around 4:30 - 5.
A few years ago, my math teacher told the class that if we came in during a Studyhall, and could solve the rubix cube in 20min, we would be 4% added onto our final grade. So, I spent some time memorizing the formula. I only solved it once, before I looked up what to do. :/ I'm impatient.
