Introversion is in the spotlight for the latest Humble Indie Bundle, which offers up four of the studio's titles: Darwinia, Multiwinia, UpLink and Defcon. As usual, paying above the average will net you some extras, namely Aquaria and Crayon Physics Deluxe in this specific bundle.
And if you're wondering what other fun stuff will be added to the bundle down the line, perhaps toying with a "wait and see" approach, don't sweat it. No matter when you buy this bundle, you'll get access to everything added to it -- that is, if you choose to buy the bundle. If you don't, then clearly you don't like fun games, which isn't so much a character flaw as it is just a flaw flaw.
