320 x 352 pixels, produced using a Vic-20 computer.

This image includes 24 radiating lines, drawn from the screen’s centre point. The BASIC program I developed to produce this image (which uses my 'BigArt' screen and machine-code routines) allows the user to enter the number of radiating lines that are drawn. The program then calculates the angle for each line and draws the correct number of lines around the centre point. This program was used as the basis for all of the images shown on this page.

This image includes 51 radiating lines, drawn from the screen’s centre point. There is an interesting shape forming around the centre point, from the accumulation of black pixels plotted for all of those lines.

This image has 180 radiating lines, drawn from the screen’s centre point using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.

There are interesting ‘moire’ patterns forming around the centre point, mainly as a result of the way that the lines are drawn over the array of pixels (often as short sections of straight lines), as well as the overlapping of line segments that occurs close to the centre.

This image has 500 radiating lines, drawn from the screen’s centre point using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.

This image has 5900 radiating lines, drawn from the screen’s centre point using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.

There are interesting ‘moire’ patterns forming around the centre point, mainly as a result of the way that the lines are drawn over the array of pixels (often as short sections of straight lines), as well as the overlapping of line segments that occurs throughout the whole image.

This image has 18000 radiating lines, drawn from the screen’s centre point using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.

This image has 2,205 radiating lines, drawn through 90 degrees from the screen’s top-left point using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.

There are interesting ‘moire’ patterns forming around the top-left point, mainly as a result of the way that the lines are drawn over the array of pixels (often as short sections of straight lines), as well as the overlapping of line segments that occurs throughout the whole image.

This image was formed from drawing radiating lines around a quarter of a 640 pixel square (drawn through 90 degrees from the screen's top-left point). The lines are drawn using a special draw mode - ‘exclusive-or’. The ‘exclusive-or’ drawing mode looks at what value is under the pixel that is wanted to be plotted, and if it is white, it plots the pixel as black, and if the pixel was already black, the mode plots the pixel as white.
