This batch of tilt-shift images was made with the Art&Mobile TiltShift Generator. You can use it via the Web or download it via AdobeAir. It’s a free application, but the effect isn’t as striking as it is when done with Photoshop. It’s good for experimenting with, though.
These look good, but I agree with you about Photoshop after seeing your first batch. I’d like to give this a try sometime.
