Equipped with only a crayon and low-voltage Speccy, Thurstan has somehow managed to put together another jumble of letters and numbers which, when typed in in the right order, produces astonishing results. This time it's a short routine, with built-in demo, designed to add a bit of sparkle to your screens (which is why it's called Sparkle in fact).
