Creativity like a faucet

I need some help on my next composition. I have a few ideas, but I can't seem to narrow it down. Lets see how many votes I get for the choices:

1. The Four Horsemen - A band piece with a programmatic nature of the 4 horsemen of the Apocalypse
2. A choral piece with the text of a psalm (need suggestions on a psalm)
3. Another addition to my extremely successful and popular Animal Song Cycle (need suggestions on an animal, something exotic and/or random)
4. Dante's Inferno, Circle IV - a piano solo with programmatic nature of Dante's travel through his version of Hell.

So I have several things swirling around to work on, but I can't decide which one to actually start. I need some much need inspiration.

Waiting for the mood to strike me...
