Program | Name | Description |
1 | 4-Point Star | Star pattern with hole at centre |
2 | Radial | Alternating yellow and orange radials from screen centre with a central circle |
3 | Recursive Squares | Full screen pattern |
4 | Deltoid | A program based on parametric equations. Only 2 lines of trigonometry define the shapes co-ordinates |
5 | 6-Point Spirograph | Based on the Deltoid another superb pattern relying on parametric equations |
6 | Lissajous Curves | |
7 | Wool Ball | Only a small amount of code is required to draw this simple and effective graphic |
8 | Spiral 1 | Simple spiral pattern |
9 | Recursive Radials | Attractive pattern of different sized circles formed by radial lines |
10 | Polygon | A neat bit of programming that draws a standard polygon but with all its corners linked with straight lines |
11 | Multi Circles | An unusual pattern formed by 4 main circles with each containing a further 7 circles decreasing in size and having a common circumference |
12 | Polygon (Colour Filled) | A 20-sided polygon created with the PLOT command (85 - Triangle fill) |
13 | Petals (Colour Filled) | Petal shapes formed from 6 circles |
14 | Polygon (concentric) | Concentric polygon pattern starting from a pentagon to a 34 sided polygon |
