Some further Ranstak experiments

When exploring possibilities there are often avenues of potential that are not selected for immediate further investigation.

This example shows the use of helix shapes that did not have random characteristics. Possibly plotted before I tried changing the parameters of length, amplitude and frequency randomly.

Aware that In a Ranstak composition some of the randomly oriented shapes would have the same orientation, but that this was hidden by the distortions of perspective projection, I thought of getting lines drawn joining the local orgins of those that had gone through the same local transformations. This is shown in the lower of the following two drawings.

The next work exploited the reasonable accuracy of the plotter. It enabled me to write a program in which part of the database representing a drawing could be rendered in a different colour to the rest. The curves of the helices continue through the change of colour at a chosen boundary. In this case the boundary is square and leads to a neat figure-ground ambiguity.
