OrbySPV (Sequential Panoramic Viewer) gives you the ability to create highly interactive virtual tours, similiar to the Google Maps Street View, using your own panaromic images. The Orby experience is not like the other virtual tours that you may have seen around the Web, where you stand in one spot and look around in a static 360 degree bubble. Orby has that ability, but instead of standing in a single position, you can actually walk around in the captured environment, stop at any position, and zoom and rotate as much as you want.
ExifTool is a platform-independent Perl library plus a command line application for reading, writing, and editing meta-information in image, audio, and video files. It supports many different types of metadata including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, and ID3, as well as the maker notes of many digital cameras.
Tioga is a Ruby library for creating figures and plots with high quality text and graphics in PDF format. Text is processed directly by TeX (not an emulation), and the graphics covers a broad range of PDF features including images, curves, clipping, and transparency. Tioga is relatively easy to use, complete, and well documented.
Python Mesh Viewer is a very basic tool to display and play with 3D models. You can either construct them in the code (by defining points, triangles, and quads) or load them from a file. Currently, the only file format supported is the ".mesh" format from the closed source software medit. The rendering is done with absolutely no hardware acceleration (no OpenGL).
Renoise is a sophisticated music sequencer and audio processing application. It's an all-in-one music production environment for your personal computer. Based on MOD tracker software, its primary use is the composition of music using samples, (in WAV, AIFF, FLAC, Ogg, and MP3 format), plug-ins, and MIDI/OSC sequencing of VSTi/AudioUnits soft synths.
dirogg is a small script to migrate your entire music collection to the Ogg Vorbis format. It's a recursive script, meaning that you run it from the root of your music collection, and it will automatically convert your MP3 files to Ogg Vorbis (ogg) files. If you wish, it can also remove your MP3 files after conversion.
Liquid PCB is a computer aided design application for designing printed circuit boards. Unlike other PCB CAD applications, you are not restricted to straight tracks and 45º angles. Instead, you can freely draw tracks any way you like, and the tracks themselves will move and bend as required to maintain your design rules. Vias and components are also free to move and rotate. The user interface exposes all functions through the multi-directional expanding mouse menu and the keyboard instead of through icons and menus.
