I put together a 'landing page' for the intelligence explosion concept similar to Nick Bostrom's landing pages for anthropics, the simulation argument, and existential risk. The new website is IntelligenceExplosion.com. You can see I borrowed the CSS from Bostrom's anthropics page and then simplified it.
Just as with the Singularity FAQ, I'll be keeping this website up to date, so please send me corrections or bibliography additions at luke [at] singinst [dot] org.
Probably too silly to use here, but one thing that comes to mind is a brain reshaped to have the form of a nuclear mushroom.
That might be misinterpreted to mean "mind blowing."
