October 27 – 300.

Celebrating image # 300 (65 more to go!) – from – very old (the background tiling) – to very new (the abstract shape)…

JavaView – A periodic minimal surface constructed by German mathematician Karl H. Schwarz using the following two principles:

  1. If part of the boundary of a minimal surface is a straight line, then the reflection across the line, when added to the original surface, makes another minimal surface.
  2. If a minimal surface meets a plane at right angles, then the mirror image of the plane, when added to the original surface, also makes a minimal surface.

Floor tile– same surface taken through a Lagrange spin filter.

Background: Hubble telescope. Incoming Comet ISON. Its glare can be seen at the left bottom of the foreground object.
