software

Eureqa is a software tool that allows to derive formula(s) from data, using Symbolic Regression.

Everybody can use it. Here is a(n) (gentle) introduction:

The beauty of fractals. Interactive and in real time.

Available for IOs based (mobile) machines.

The best place for (ZX) Spectrum related resources.

The, now defunct (?), Project Looking Glass still holds (the good) promise of a more 3D(ish) desktop environment.

A planetarium for the computer. A commendable open source initiative. And is also free. As in beer.

Dubbed Haiku, an ongoing open-source effort to keep BeOS, and all its design virtualities/philosophy, alive (albeit indirectly).
