ImageJ is an image processing program inspired by NIH Image for the Macintosh. It can display, edit, analyze, process, save, and print 8-bit, 16-bit, and 32-bit images. There are modules for biology, astronomy, nuclear medicine, physics, and more. If you can take a picture of something, whether with a microscope, a telescope, an oscilloscope, an xray machine, or a scanner, then this program will let you enhance, manipulate, and measure the results.
socket_wrappers is an improved version of tcp_wrappers. The improvements include changing from K&R to ANSI C, removing unneeded compatibility libraries, separation of the public and private API, prepending tcpd_ to all private functions and data to prevent name collisions, updates to signal handlers so that the application's handlers aren't tampered with, dropping supplemental groups, and some build and man page improvements. Applications compiled with this library should be smaller, too.

Using gravity, dominoes, bowling balls (and other balls), ramps, balloons and cola bottles primed with Mentos, The Butterfly Effect invites you to solve physics puzzles and knock over the bowling pin at the end. In case you get stuck, the friendly Post-it Boy has left his clues where they might come in handy. This game is not entirely unlike the famous game "The Incredible Machine".
