Finally bit the bullet and invested in a whiteboard so I can quickly build and sketch ideas and maps for my final projects. Taking the format suggested by Chris for outlining my project ideas, I've created the map below.
The cluster of post-it notes indicates whereabouts certain ideas, technologies, people, etc. sit on my map. Currently, there is a lage cluster alog the social-technological-information lines, so I need to expand quite a bit on the time-information line.
