Bersoft Image Measurement is an application for measuring digital images. To measure an image, simply click on the image to define control points. The program will automatically calculate the area, perimeter, angle, radius, or length, depending on the measurement tool that is selected....

LifeLab is a Mac application for exploring John Conway's Game of Life and other cellular automata. CAs were first studied in the mid-1950s by Stanislaw Ulam and John von Neumann. The subject became much more widely known in 1970 when Life was described by Martin Gardner in his Scientific American...
