Let's do this! I usually have too many ideas in my head to implement, so feel free to steal some.

My theme for today is moss.

1. make a game with the graphics consisiting out of macro photos
2. make a living picture frame filled with moss
3. make a Twitter bot retweeting moss pictures
4. create a miniature landscape using moss
5. establish moss gardens in Europe (common practice in Asia)
6. create a room where every piece of the wall is moss as art installation (2x2x2m)
7. use moss for product photography
8. make a "floating" moss sphere, hanging on a nylon rope
9. make a book cover out of moss
10. create a photography where it seems the models finger grows full of moss once she touches it
