who the heck is Notch?

Notch created a popular pc game called minecraft where you mine blocks and build things. It became very popular and made him a multi-millionaire.

This demo has a little bit of minecraft in it. :)

thank you very much!

How is that a bad question. Yes he could have looked it up but it wouldn't have hurt to have "Minecraft creator Notch trying jsFiddle" as the title, would it?
