Sam Potts has put together a seriously awesome map of connections and relations in Infinite Jest.
You can download it here, but even better, Sam has had it professionally printed so you can buy a copy to hang on your wall! Looks like the perfect present for a fans of Infinite Jest.
Thanks, Sam!
UPDATE 23/1/11: My copy of the diagram arrived during the week and it is magnificent. When I was asked to give some feedback while it was in production I was working off an A3 sized version that did not do it justice. At full size it is stunning. I'm getting this laminated and up on the wall ASAP - but I'll have to be careful not to put it too close to where I need to get things done, I can't help but stare at it.
Well worth the purchase price. Great stuff, Sam!
