ted (Tiny EDitor) is a lightweight commandline text editor designed for scripting. It's intended to be an easier-to-use alternative to "ed". It is lightweight, scriptable, and easily harnessed by shell scripts, but doesn't suffer from the chronic user-unfriendliness that characterizes ed. It is also slightly more featureful than ed, and includes multiple editing buffers and built-in script handling.
teepeedee is a small, fast, single-threaded file server. It is very scalable, and can serve multiple files over HTTPS, HTTP and FTP simultaneously, listening on any number of ports and providing entirely different views of the filesystem to different users. It supports most of the draft-ietf-ftpext-mlst-16.txt FTP extensions, as well as EPRT, EPSV, AUTH TLS, and HTTP 1.1 persistent connections.
telepathic-critterdrug is a fork of Critterding, an artificial-life simulation, with five drugs added and a substrate for two kinds of telepathy. The critters are exposed to a secondary retina they can all read and write, using sensors and motors for high intensity or only the power of the minds for lower intensity, though drug use will modulate it. They can blink this and their main retina as a minor grace. The two blue tablets work on inhibitory neurons, and the red ones, excitatory. There is also a purple potentiator.
tenmado is a vertically scrolling, late 1990s style (i.e., a massive number of enemy shots against a smaller-than-it-looks spaceship) shoot 'em up game. A very accurate collision detection makes it a game of dexterity. If something looks like a triangle, it is a triangle, not a rectangle of similar size. However, surviving is only 20% of the game. The main feature of tenmado is the "color chain bonus". You can get a very big score (about 100 times bigger than a normal enemy-destruction point) by destroying enemies of the same color successively. It is easy or difficult depending on how greedy you are.
TerminatorX is a realtime audio synthesizer that allows you to "scratch" on digitally sampled audio data (*.wav, *.au, *.mp3, etc.) the way hiphop-DJs scratch on vinyl records. It features multiple turntables, realtime effects (built-in as well as LADSPA plugin effects), a sequencer, and an easy-to-use GTK+ GUI.
