Hemisphere Games' award-winning Osmos is on sale today at Steam for only $2.50. This isn't the first time that Osmos was offered at such a low price (Steam had discounted it down to $2 in the past), and it is quite likely that you already own a copy from purchasing one of the many promotional indie game bundles that it had been included in.

Coincidentally the Osmos development team had also recently announced that their game will is coming out on the iPad this July 8th (with the iPhone version to be released one month later). Porting it to the iPad and iPhone means a new control scheme, and you can see how that works in the video we've embedded after the break. (source: GameSetWatch)
