Eyefi I2 is an API for the abstraction of all common image transformations (thumbnailing, scaling, borders, etc.) into an XML file. Through a simple PHP API, images can be loaded through such a transformation to generate and cache a modified image. By stacking the image operations, very complex transformations can be accomplished, incorporating source images, generated text, image overlays, and more.

The Lightflow Rendering Tools are a set of tools for advanced photorealistic rendering, aimed both at scientific visualization and artistic or cinematographic animation. Their features include: radiosity, caustics, volumetric rendering, hypertexturing, real displacement mapping, and NURBS.

Pymousetrap provides access to a C-implemented shared library that efficiently stores information about a 2-dimensional grid (a mousetrap). The mousetrap is integer resolution, and supports works very similarly to graphics libraries; mousetraps can be 'blitted' onto each other, with transparency. This code was written with the intent to simplify the way mouse click events were handled, but probably has other uses.
