Random walks

I tossed coins to see what direction to draw a line in.

If it was heads + heads, I drew a red line going right.
If it was tails + tails, I drew a green line going left.
If it was heads + tails, I drew a blue line going up.
If it was tails + heads, I drew an orange line going down.

I also wrote a quick script in Processing to get the computer to do the same.

The computer can draw better than I can! Also, the computer did not have the problem that their orange pen was starting to turn a bit purply.

Random walk variations

More attempts at using Processing to create random walk variations, using different colours, etc. (Computer decides whether to draw left, right, up, or down.)
