It's a good thing I killed my CPU attempt after 2 hours then!
I would have definitely died in that sandstorm!

I don't know shit about stuff l7ke this, but it's interesting. What does this mean?
- One way to get the data is to render to a (hidden) surface/canvas. It's just bytes to the computer, so just dump the result data in the display buffer. Then you take a "screenshot" and interpret the RGBA values as data.
  
  Thank you!

Brute force what? Part 2 of what?
- Erm, do you know where you are?
  
  I can't speak for the other guy, but I definitely don't!
