its very kind that you mention my site.
All my post its were drawn while doing something else in an ad agency: phone calls, meetings, brainstormings-if you are looking close you will find lots of valuable information hidden on these notes like phone numbers, comments etc.-but you will also find my different staes of mind, anger, distraction, making fun of people…the whole thing started subconscious like the swirls and ornaments a lot of people draw on desks and everything else in reach when they are doing phone calls.I have been collecting my post its since 1993 and at this point there must be around 25.000 of them.Kind regards from Ulf
