I-Fluid
It could so easily have been a new euphemism... instead it's an action platformer from French independents Exkee, in which you pilot a drop of water across a series of obstacles. The 121mb (around nine Peggles?) trial download can be found here. I had a quick poke at it and found it to be charming. Use watery things to increase your droplet size, and avoid being mopped up by paper or biscuits. It needs a little better signposting, but I like it both the peculiarly realistic visuals and the simple control system. Go take a look. Trailer after the hop.
