The games are being released as part of a bundle of code called the 'Humble Indie Bundle,' and include the following games: Aquaria, by Bit Blot; Gish, by Chronic Logic; World of Goo, by 2d Boy; Lugaru, by Wolfire; and the Penumbra series by Frictional Games. Gamers can pay whatever they want for the code, and can also choose to donate part of their payments to charities such as Child's Play or the Electronic Frontier Foundation. To date, contributions total $1,070,370 from 117,764 contributors. Contributions are itemized by game platform, with Linux gamers contributing just less than one-quarter of the contributions, almost equal to the contributions from Mac gamers and about half the contributions from Microsoft Windows gamers. These contributions have exceeded the companies "craziest expectations" according to a quote on Wolfire's Humble Indie Bundle website."
