Petr Vlk is from the Czech Republic and creates hand-made vector doodle symbols which he sells in a kit on his website http://doodlekit.imagiag.com. These symbols can be used for presentations, brainstorming sessions, flow charts, etc.

In the image above, Petr is working on rough ideas for some custom vector doodle symbols. When he granted me permission to use his photo, he told me that the Rhodia dotPad was his daily tool.
