Dear Pieter-Tjerk,

Nice to see your work on the Web! Two years ago I saw your neon-circuits 
(counters, dividers etc) on the "Dag van de Amateur" (a Dutch 
HAM-vention). Unfortunately you were not present at your display, but I 
was very interested. Now I have a chance to have a close look at your 
circuits!
