In 1981 Topologika’s Brian Kerslake wrote a BBC program called 'Letters', which drew lower-case letters on the screen. The shapes were 'borrowed', with permission, from a book by Chris Jarman who, at that time, knew nothing about computers. Now he’s writing CD ROMs! We are delighted to offer you his first CD ROM, the 'Art Lesson', Imagine, a power-packed art program with lots of unusual maths features, and a great selection of Clip Art.
