You already know the deal. The sale is coming to its end and you now have exactly one day left to purchase (…more copies of…) the “Humble Indie Bundle”:

Somehow missed the bundle altogether?

• Contains five full games: Aquaria, Gish, Lugaru, Penumbra: Overture and World of Goo (plus Samorost 2 as a late bonus from Amanita Design)
• The profits all go to the developers as well as two charities: EFF and Child’s Play.
• You pay what you want to whom you want.
• The games are cross-platform and DRM-free each. Arstechnica recently chatted up Jeffrey Rosen on the topic.

Notably, for the duration of the campaign, Frictional Games are also offering the remaining two Penumbra games, Black Plague and Requiem, at a 75% discount. Furthermore, you can also preorder their forthcoming project, Amnesia: The Dark Descent, at 50% off (a great idea - the team will produce additional content if 2000 preorders are made before the 31st; the meter currently sits at an even 1900):

While you’re at it - and even if you’re not buying the bundle - please also remember to subscribe to Wolfire and Frictional Games’ development blogs; they contain what can only be described as a cornucopia of information, both intriguing and useful, for indie game fans and developers alike.
