OmniDazzle for Mac offers a set of desktop enhancements that include visual effects for aiding in presentations or just having a little fun while sitting at your computer. Even though most effects work well, some are a bit glitchy.
Installation was the regular matter of downloading and copying to the Applications folder. When we launched the app the first time, it brought us right to the help screen, which offered a good breakdown of what the app does and how to use it. OmniDazzle for Mac only allows one effect to be active at any time, so we selected our first one--Pixie Dust--by pressing the associated hot key combination. The controls for each effect are explained well and easily reconfigured. We cycled through each effect and tested them out. There are some useful tools for presentations, like Scribble, which allows for drawing on the screen, and Focal Point, which highlights an active window or just an area around the mouse. Most of the tools are just for fun, though, such as the ability to flash a Batman-style "sound effect" on the screen like "POW!" or to overlay a Sonar, which is used to locate the mouse pointer. We found a few of the effects to be glitchy in their application, causing odd flashes and remnant pixels to remain on the screen until the effect was deactivated.
It's a mixed bag of tricks, but OmniDazzle for Mac could very well have staying power for those with the need to add a little visual fun to presentations.
