The main reason for mentioning it is that it includes the particularly wonderful Osmos. I already have it (twice, via HumbleBundle, once for the desktop and once for shiny) and I recommend you check out the video.
I'd happily buy it again, but the other games don't inspire me (a party game which needs you to have game controllers, a Jewish mystery themed point and click, and what looks like a platformer).
Current minimum price is £2.57, and Osmos is worth more than that alone.
