Enzymind Labs

Just a note that my hosting provider was doing some upgrades and changes on their servers that caused enzymind to not be available for the past day or so. Seems to be all fixed now.

I wrote a simple modification of my program L_system_tiling so that it could replace pixels in an image with any particular pattern. So, for example, starting with a yin-yang pattern with three colors (black, white, gray):

Seems to work OK. Another thing that caught my attention was that the tool was built in Adobe Flex. It has a nice interface...second image is a vector version of the first picture.

Announcement on cspan regarding E8. I had not been aware of this structure it has some interesting geometrical features:

Had a difficult week and a half, felt sick most of the time and it was hard to concentrate. One productive project got done, a tesselation with a "universal tile pair" -- any square tiling with the related pair results in smooth contours. I also reworked a brain animation as part of a demo for a possible public display commision.

Various curiosities:

Thought I'd stop using the date as the title of blogs for while.

A video to an impressive video which describes the latest technology in cancer treatment.

Also on an unrelated topic a nice 'zoom out' video demonstrating the depth of digital images. 

 

BBC documentary on time and mortality. Interesting informal experiment is done to compare perception of time for older vs younger folks.
