Fotoxx navigates an image collection using a thumbnail browser to choose images to view or edit. Edit functions include brightness, contrast, color, gamma, white balance, tone mapping, red eyes, sharpen, blur, noise suppression, smart erase, trim (crop), resize, rotate, add text, bend/warp, many art effects, HDR, HDF, stack, and panorama. Edit functions use movable curves and sliders. Feedback is live using the whole image. RAW files can be edited and saved with deep color. Areas or objects can be selected using freehand draw, follow edge, and tone matching. Selections can be edited in place with adjustable blending. They can also be cut and pasted into other images. Any metadata can be edited, reported, and searched (filenames, tags, dates, geotags, comments, captions, ratings, etc.). Collections (arbitrary subsets) can be defined and viewed. Batch functions are available for rename, resize/export, RAW conversion, and more.
Rapid Photo Downloader is an application for professional and amateur photographers, designed for use on the Linux desktop. It can download photos and videos from multiple cameras, memory cards, and portable storage devices simultaneously. It provides many flexible, user-defined options for subfolder creation, photo and video renaming, and backup.
Lynkeos processes astronomical webcam images. By stacking the best images, the signal to noise ratio is increased, and details lost in the noise of individual images become visible in the resulting image. This software accepts, as input, QuickTime, AVI, and MPEG sequences, or still images, in any image format supported by its active plugins (TIFF, FITS) and Cocoa. It generates a 16-bit RGB TIFF or a monochrome FITS image as output, to be further processed with some all-purpose image processing application.
MuseScore lets you notate and compose music easily with your keyboard, your mouse, or a MIDI keyboard. You can print beautifully engraved sheet music or export it as PDF or PNG. You can play your score, transpose it, and save it as audio or MIDI file. MuseScore also supports MusicXML to let you share your composition with other scorewriters. MuseScore is often advertised as a cost effective alternative for Sibelius and Finale.

Tux Paint is a simple and entertaining drawing program geared towards young children. It has a simple interface, sound effects, and a cartoon character (Tux, the Linux penguin). Along with drawing brush strokes, lines and shapes, you can also enter text and place "rubber stamp" (or "sticker") images on the picture. Tux Paint is extensible, and could be useful in an educational environment (such as a grammar, elementary, or grade school). It's portable across numerous platforms, and runs well even on slower systems like the Pentium 133MHz.
The Ecere SDK is a cross-platform toolkit for building software applications. It currently runs on Windows, Linux, Mac OS X (through X11), FreeBSD, and the Android OS. It should run on other Unix platforms with minor testing/tweaking. With the Ecere SDK, you can develop applications once and deploy them on all supported platforms alongside a lightweight runtime environment. It introduces eC, an object oriented language derived from and fully compatible with C, compromising neither runtime performance nor ease of use. A built-in 3D engine supporting both Direct3D and OpenGL is fully integrated.
