Hi ...

I'd like to implement Langston's Ant in Ruby. To do this I need to
display the path of the ant on the screen. Basically this consists of
setting the color of a (large) pixel to one of a couple of colors.

What's an easy way in Ruby to draw some pixels on the screen or in a
window.

Hint: No "easy way" could possibly include the sequence of characters
"tcl".

Thanks!
