Hey wow cool look at this. This weird little game popped up on my stumble account and I've been addicted to it. This website "Vector Park" is filled with all kinds of seemingly simple/deceptively complex little interactive animations. Spider in particular applies a really neat way of looking at depth. When you move your mouse up, it moves the spider not just but farther away. Down = closer. It's a fun little experiment and somewhat mesmerizing. Enjoy!
