Image Style Verification in HTML DB

I saw this posting by John Scott this morning about Image Style Verification in HTML DB:

Its meant to be used to stop those automated spam bots submitting any form you may have. (Just like the image you get when posting a comment here.)

Nice bit of work, although it has a dependency on SVG in the browser, and is not a real image. Hopefully soon SVG will be standard in browsers. (I made a posting previously about SVG in Firefox 1.5.)
