There are many photo-gallery programs available. Zoph is different, as it concentrates on the management of large collection of photos instead of just showing them on the Web. It can store a lot of information about your photos, including the regular EXIF info, photographer, location, title, description, rating, and the people in the photo. Photos can appear in multiple albums and categories. Additional features include search, slideshows, lightboxes, email, access privileges, and multiple languages.
ColorChip is a class for working with color in a more convenient manner than the basic RGB and Hexadecimal triplets often encountered in programming, especially Web-oriented programming. It allows you to define a color using RGB, HSV (Hue, Saturation, Value) or a Hexadecimal string. ColorChip objects have properties for all three of these color models, as well as methods for adjusting both RGB and HSV values. These methods automatically update all of the object's properties. Additional methods exist for getting color compliments, triads, and the nearest Web-safe color.
Evolvotron is an interactive "generative art" application to evolve images/textures/patterns through an iterative process of random mutation and user-selection driven evolution. If you like lava lamps, and never got tired of the Mandelbrot set, this could be the software for you. It's implemented using Qt, and is multithreaded.
