Pulse Apple

Freeverse publishes the Think utility

Think locks the windows of other applications to avoid distractions and stay focused on the task at hand. This utility gives you the ability to highlight the Mac application that is currently being used, so that it is the only focus of attention. Any other application can also be brought to the fore temporarily.

Think is free and available as a Universal binary. Requires Mac OS X 10.4.3 or later.
