Draw a multitude of shapes in whatever colour you choose and to a musical accompaniment with this simple program written for the Electron by 12-year-old Toby Jefferys of Peterborough.

Use the Z, X, K and M keys to move your point round the screen and use the numerals from 1 to 8 to change the colour of the line you are drawing.

Painter will also run on the BBC B.
