Bitku

A totally free simple storyteller, a comic creator, an art toy, a new way to express yourself in pixels... BITKU is all or none of the above.

Here's how it works:

1) Choose a theme
2) Get 10 random cards related to that theme, each of which has a single background or multi-frame object
3) Make a 1-4 panel comic or story with the contents of those cards. Add text, recolor anything, enlarge, rotate, etc.
4) Save your creation as a PNG and share it with the world!
