Wanderer Links
A short list of other people's work worth wandering off to: tools and pages that share this site's fascinations without living in it.
Astrology·Open Source Software
RadixPro / Enigma
The site of a friend, Dutch programmer, author and astrology researcher Jan Kampherbeek: one of those rare, amazing brains who moves easily between rigorous research and hands-on code. He builds Enigma, an open-source astrology application, and collects the data behind it.
Astronomy·Observation
ARITAKA Astrolabe
An interactive astrolabe that visualises the sky from a chosen location, with rise, transit and set times and a planetary-station marker scaled to each planet's own retrograde speed.
Astronomy·Alignment
Heliora
Places a pin on a map and shows when the sun, moon or planets will line up with the landmarks around it: full moons over summits, golden-hour windows, and upcoming eclipses.
Mathematics·Geometry
Hopf Fibration
A 3D visualisation of the Hopf fibration, the mapping of a 3-sphere onto a 2-sphere, drawn out as linked circles in space via stereographic projection.
