This is the Lensbaby Spark for Canon cameras (here) priced at $87.95.
"A fun and affordable way to capture selective focus images with a digital SLR. Spark features a unique selective focus optic and a tilting lens body, allowing the aspiring amateur photographer to capture creative images in-camera that have a sweet spot of focus, surrounded by blur. Spark is a lightweight, all plastic (except for the optic, which is a multi-coated glass doublet) 50mm selective focus lens with a f/5.6 fixed aperture available for Canon and Nikon DSLRs. Spark is the perfect entry point into the Lensbaby system for photography students or newer photographers looking to expand their experiment and add a creative lens to their camera bag. Spark is compatible with the rest of the optics in the Optic Swap System, and with all Lensbaby 37mm threaded accessory lenses." (Description info from amazon.com.) Something tells me you can arrived at nearly the same results just using your manual settings....really, how did they do this before this gadget came along?!

Anyways, this was something I had not known about
and wanted to share. Now I can move on to Project 6 ~ Break the Rules.
If you have used a Lensbaby, please let me know what you think about it.
***** Photography Notes *****
1) Choose a small f/number (wide aperture) if you want lots of blur and a big f/number (small aperture) to reduce blurring. Fitting no disc at all gives you maximum edge blur and minimum dept of field.
2) "Like all creative gadgets, the Lensbaby Composer should be handled with care, otherwise there's a danger of overkill." (Don't over use or it becomes redundant in you photos, I suppose.)
3) It works best on simple, bold subjects - cars, architecture, people and still lifes. The key is to experiment, and remember that only a small part of the image will record in sharp focus. This doesn't have to be in the center, but it should be where a important part of your subject is, otherwise the final results may look a little odd.
4) Automatic exposure is possible by shooting in aperture priority mode for the vast majority of digital and film SLR cameras except certain Nikon and Fuji bodies.
