Lost Winds looks like it'll be one of the more impressive WiiWare games to me. Basically, you use the Wii Remote Cursor to control the wind, and using the wind will cause various things. You can draw a line of wind, and while you're doing that, time slows down for you. Things get caught in the line of wind that you draw, such as elements from the environment. So, if you draw a line of wind with the starting point be some water, you can guide to water to wherever you want it.
Another way this is used is like a cannon, sort of. You draw a circle around an enemy, and then point the direction you want it to go in. Or, if you aren't drawing a wind line, and time isn't slowing down, you just move the cursor in various directions to push things around. This is how you jump, but it can be used for other things, too, like pushing enemies around.
Making those lines of Wind reminds me of Kirby Canvas Curse, but the game reminds me more of Okami.
Here's a link to Gametrailers videos of the game. I highly recommend you take a look.
