These quicktime movies were created using the Create Movie... function in ACSLogo. Click on the picture in each case to bring up a window containing the movie.
Most algorithmic pictures have some sort of input parameter which affects the appearance of the final picture. You can use movies to show how the picture changes with changes in the parameter.
With fractal pictures like the Koch Curve, the amount of detail is determined by the Level parameter. This animation shows how the curve changes with increased level. You can see the change best if you single-step through the movie.
This Bridget Riley-type picture is built like a series of concentric circles, but some of the circles are offset. I changed the procedure so that the input parameters affect the offset in the x and y directions.
These tiling-type patterns were all produced by the same procedure, with different input parameters. The movie shows how the pattern changes with variation in the parameter (5.7M).
These two patterns are done using the same algorithm. In each case, a pattern is overlaid with slightly different versions of itself.
In this example, text is decomposed into paths which are then coloured separately.
This is a colour version of the Bridget Riley movie with dropshadow.
A couple more tile animations.
This is a simple flash effect, created by drawing a series of radial lines and rotating them.
Two more tile animations. One is just a coloured version of the other.
Animation of the drawing of a letter S, created using the SetLineDash command.
