This requires a pen like the 'flytop', but modified to add a camera, and also have the computer control the release of ink.
First, select a picture to be drawn is by pointing the camera lens at a suitable photo.
Next, scribble with the pen to draw lots of diagonal lines over the paper...
The pen controls when to release the ink in order to create a sketch type drawing, similar to the processing done to a photograph by the Photoshop sketch filter.-- gtoal, Feb 10 2006 'flytop' pen http://www.flypentop.com/ [Ling, Feb 10 2006] Handheld inkjet print gun http://www.youtube....ure=player_embedded [xaviergisz, Jun 05 2011] I'm stickin' wid my Rasta pen, mon.-- DrCurry, Feb 10 2006 Sort of a ultra-portable printer. If a black ink cartridge was used, with built in nozzles (like on an Epson inkjet), and some kind of position measurement, it could work like those hand-held scanners but in reverse.-- Ling, Feb 10 2006 [ling] That link's brilliant! - I want one.-- Dub, Feb 11 2006 shown in the movie "I, Robot", so this may be a "WIBNITTISIAMWR" or whatever.-- sninctown, Feb 11 2006 In the film "I robot" it was the robot doing the work rather than the pen.-- fridge duck, Feb 11 2006 Nice link, [ling]. That is very cool.-- moomintroll, Feb 11 2006 Hey, [gtoal] should get all the credit: I just did a search on his first sentence.-- Ling, Feb 12 2006 Don't worry.
