Indie bundles are popping up everywhere. You can hardly misstype a URL without getting one these days.

Little big bunch is the latest of the lot.
This one contains:
Frozen Synapse
Explodemon
Serious Sam: Double D
New Star Soccer 5 (what we Europeans like to call football, because you actually use your feet more than your hands)
Oddworld: Munch's Oddysee (is this even indie?)

Their website is currently down though.
