From the developer:
Eidetic helps you take beautiful screenshots with just one click. It is a small app that allows you to take screenshots from the menu bar or the today view of OS X. A click on the left button shows its menu. Right-click on the Eidetic icon in the menu bar to take a screenshot.
You may want to check out more software for Mac, such as iGrabIt, GrabberWindow or NewTek iVGA for TriCaster, which might be similar to Eidetic.
