Hello World,

I put up a 2.5m wide polargraph over the weekend for an exhibition and made a little big experiment with the new polygonizer function 😎
And my second little (sparkfun) servo served me very well! 130.183 polygons and penlifts in approx. 76hrs ! (and the same amount in testing before...

first photo is by "Ed Chapon"

artwork from there:

another CMYK experiment with Dullbit's amazing " Death to Sharpie" script! -> http://www.dullbits.com/drawbot/drawbot
still need to fiddle around with the parameters to get better control over the transition zones....but the abstraction is also nice anyway (in my eyes at least 😎 )

original photo is from here: https://repeatingislands.files.wordpress.com/2015/08/lionfish1.jpg

both images drawn with each a new set of Stabilo point 88 pens in CMYK (57, 56, 44, 46)

big fish on A2 "FABRIANO Academia 200g/m²" front side (a bit too rough for Stabilos, will try rear side next time)

small fish on A3 "Zeichen Austria, Edition Dürer Tuscheblätter 200g/m²" front side

PS: little servo still up and running <3

These drawings are exceptional!

Thanks guys!

Josep, In case of the fishes, as I am no pro in processing, I just fiddled around for a very long time with the parameters of Dullbits script...the colour splitting I did in Photoshop by simply changing the mode to CMYK and splitting the channels. 😎 I then processed the 4 different greyscale images separately... always looking for a workaround if possible...

krummrey, I started working on a new "plug and play" penholder that clamps the pen automatically...based on Sandy's design...but it doesn't really work yet...need some more iterations...will upload it as soon as I am satisfied with it....
but I anyway only needed to put 4 different pens (that's why I am so obsessed with CMYK lately)...within a total of 34 hrs and 35 mins in case of the A2...so changing a pen for a couple of minutes wouldn't really blow up "printing" time that much... 😉

btw, that's also an interesting design, I think:
