I liked this a lot. Very good first attempt; I'm happy to have tried out this little CPU-sucker. Personally, I never quite got the hang of printing colours to the terminal -- but then I never sat down with any instructions, either :o)

The obfu's not too difficult to figure out with a sharp eye and a little patience, so I'd say let the curious figure it out themselves rather than print a spoiler. As with any good obfuscation, making sense of the code is where all the fun is.

Keep up the good work,
LAI
