My only concern is that the wiper doesn't go fast enough for it to wipe properly like this. I guess it either doesn't rain hard in Pennsylvania or you aren't bothered by not being able to see very well. Personally, I like knowing that my wipers wipe effectively when I need it. The Mercedes wiper is cool, but its very complex, and I wouldn't want to deal with the potential of it breaking. The passenger only option is rice, and the wipers probably work great now.
If you want to make a cool looking mod, make a custom cowl and take the wipers off something like a Passat (the really small, covered wipers) and mold the cowl such that they appear flush with the cowl, making it really sleek, while still 100% functional.
