The Humble Bundle crew has one week remaining (as of this writing) for their most recent offer: The Humble Android (and PC and Mac and Linux) Bundle.
Games included in this version:
Canabalt
Zen Bound 2
Cogs
Avadon: The Black Fortress
Swords & Soldiers (if you pay more than the average of [currently] US$6.41)
All games work on Android devices in addition to the usual PC, Max, and Linux Platforms.
And all proceeds go to the charitable groups Electronic Frontier Foundation (with my strong personal vote of support!) as well as Child's Play.
EDIT: I reckon I ought to include a link to the website, yeah?
