GeneratorMania

It is not only about images. I have run across a blog that pretty much links to all imaginable online generators. For fun (such as Nietzsche family circus generator), self-esteem (the motivator), mocking web 2.0 (I have stopped to the web 2.0 logo creator, here is what it can do:

..playing with shapes (Modern art generator) or sounds, or sounds & text (Singing email generator, converts your text to singing messages) and soo many others..
For an extensive list, see the Generator blog. Have fun!
