Tiltshift! Sweeeeet - nearly Lomo
Click here and try out Tiltshiftmaker. It's an online programme where you can upload a picture, Tiltshift it (make a clear line and blur the rest) and then save it. Yes I know you can do whizzy stuff on Photoshop that gives you the same result, but this is still pretty cool. Make sure your pic is REALLY colourful though - you'll get much better results.
