Pixie dust
This one might just eat your productivity for the entire day as you stare mesmerized at the, ahem, dazzling pixie dust cascading down your screen. Pixie Dust turns your mouse pointer into a virtual magic wand creating a spray of colorful sparkles wherever it goes. You can change your pixie dust to include only a few tiny sprinkles, or turn it into a giant firehose of awesomeness. The color range is up to you, too.
Flashlight
Illuminate your screen with a virtual flashlight that follows your mouse pointer wherever you want it to go. When triggered, Flashlight dims your background and turns your pointer into a helpful, shining beacon that lights your way. You control the size and quality of the light, the color, and the background.
Cutout
This allows you to highlight areas of your screen using different shapes. Pick a shape (circle, ellipse, rectangle, or window border) to start, then move your mouse to control the size of the shape. Watch and be captivated as everything outside your selection dims. This one's great for guiding an audience during a presentation, or creating an awesomely instructive screenshot ("then click THIS button RIGHT HERE"). You can customize borders, dimness, and fill.
