<Celebrate the 600th Daily Create! Express 600 in a drawing without using numbers. (dailycreate tdc600)>
When I had the idea of drawing 600 circles I thought this might be tedious. I rather decided to use my blender 3D and tell it to just arrange beads along a curve.
The image I've used for the bead texture I've found here: http://www.techsavvyed.net/archives/2144
This again leads to the cogdog page: http://cogdogblog.com/
After an inspirational comment by @troutcolor on flickr (John Johnston) I've animated the chain.
For a further dailycreate, I again used the skull picture to make an animated gif:
<This is TDC 601! That is 106 backwards! Draw something 106ish backwards. (dailycreate tdc601)>
I took the skull picture and loaded it into gimp. I duplicated the picture and with the clone tool "erased" the ds106 letters. I put a mask on the duplicated picture the way that the letters appear when I draw on the mask. I recorded me drawing/writing ds106 with a software called bandicam then I created single images the way it is done for a gif (ds106 handbook -> gif with open source).
I loaded the single images into gimp and flipped the image horizontally (image -> transform -> flip horizontally). Finally I saved all as a gif.
