ClearCanvas and RT Objects

I'm looking at the source code for ClearCanvas and wondering aloud how hard it would be to modify to store RT objects.  For instance:
  • Current generation DICOM RT SOPs
  • Supplement 74 objects
  • Patient positioning objects
  • Next generation DICOM RT SOPs
Of course, rendering the objects in the Volume.MPR viewer would be especially cool, but one step at a time...maybe registering a replacement for ImageReview3DForm would be a logical next step.

playing with Cytoscape

and I transferred part of the SonicSpace (my old test space for theWheel) in to cytoscape and used a force-directed layout to get the following (with some manual tweaks):

I also manually changed the size of the nodes, though ideally I would like to implement a cytoscape plugin that would propagate activation changes for me.

Would also like to experiment with cytoscape web, whenever I have the time.

My Early Mandelbrot Plots (part II)

and here is another plot made with a non-speckle noise, on a color inkjet printer, circa 1991.

My Early Mandelbrot Plots (part I)

This was a plot made with a speckle noise pattern.  I think the colors were assigned using RGB sinusoidal waves (i.e. the frequency of the R, G, and B waves were varied independently).  Then the actual color was assigned based on a random value.

This was done circa 1991.  I remember there was another plot I had made with purplish colors, that I really liked, but I gave it to someone...

My Work TimeGlider

Having just figured out how to embed.  Now if I could figure how to not show the annoying introduction box...

Reading about Rudy Rucker's Lifebox

Lifebox Immortality & How We Got There

I like the fact that he talks about the lifebox as being a sort of digital-immortality lite, because it sidesteps the question of embodying a full human being (with all concomitant rights and responsibilities) in a digital form.  I think it cuts to the heart of the issue, which is that a human being, in life, has a lot of baggage that may not be desirable to transcribe to a different form.  Rather, the transcription may want to 'filter out' parts that won't translate well across time...

Plus it reminds me of what I was aiming for with theWeel and now fatline, which is an interactive presentation of the things that have interested me in my life.  Ted Nelson's Xanadu concept seems to fit with this idea.

Fatline Events

Have been arranging timelines on TimeGlider, because they let me expand / contract events based on relative importance (which of course seems to change over time anyway) which is I think one of key features of fatline. In TimeGlider I can arrange to have work / school related events on top of the timeline, and personal events on the bottom, like this:
I started contemplating the various categories of things I included on the fatline, and a set of tags that capture them.  I think the main ones are:

Using these as axes, I can define a set of coordinates for each event in this 7-dimensional space, and then perform an SOM for the events.  The SOM could be 2-D, and include time / place for each events, or it could be 1-D and use the timeline itself as one of the dimensions.
