I've catalogued over 3,000 different (but without any formal classification) exploring and capturing at random. Was a huge amount of fun but left a large set of "unclassified" patterns. The current code (Mac and PC) has been updated and the catalogue has been recovered using the original QB45 (now QB64) programming explorer. Over the last year I've re-written this for the Mac and updated the screen display to 32,000 colours. Watch this space for further developments.
