I've been using OmniDazzle since it was in beta, bought a license as soon as it was available. It's hands-down one of the most useful apps I've ever used, especially in the workplace.

As of Wed Feb 25, 2009, OmniDazzle is now totally free.

I'm not sure why they changed the license. When I bought it, I paid $15, and I assume they were still charging the same until recently. I guess by making it free, they don't have to focus as much on fixes/tweaks/updates, although the app seems to be pretty stable... since purchasing 1.0 in June 2006, they've only released a handful of minor updates, even now they're only at version 1.1.

Anyway, all Mac users should grab this utility now. It's both useful and silly, and at $0 the price is just right.
