From Amstrad Action-
"If you want to create an impressive title screen for your program then Paul James of Merthyr Tydfil has the goods. His listing hides the contents of the screen, draws a picture and then displays the screen in an interesting fashion. You can use this or similar effects to spruce up your programs."
