A group of benevolent indie iOS game developers have joined forces for an "Indie iPhone Holiday Sale", discounting their acclaimed games to $0.99 each and donating a third of the proceeds to Child's Play, the charity set up by the creators of webcomic Penny Arcade and devoted to donating toys and video games to children's hospitals.

The six iPhone/iPod Touch/iPad games include Steph Thirion's Eliss, Area/Code's Drop7, Tiger Style's Spider: The Secret of Bryce Manor, Mikengreg's Solipskier, Hemisphere Games' Osmos, and Semi Secret Software's Canabalt. Most of these titles have never been priced this cheaped.

According to Semi Secret's Adam "Atomic" Saltsman, the sale is off to a "pretty great start," and the developers might have "some special announcements" if they raise enough money today.
