Cool Graphs of Implicit Relations
This is a cool collection of graphs of relations using software called GrafEq:

For example, at the right is the graph of
There are several other cool graphs displayed here.
It is worth noting that Wolfram Alpha can graph these relations, too. For example, here is the above equation:; while Wolfram Alpha captures the spirit of the graph, the image is not as detailed or attractive as the GrafEq version.

The second disconcerting thing is the stuffed parrot, which I think needs no further explanation.
