The Virtual World in our Minds

Irving Wladawsky-Berger has a great posting on why humans like virtual worlds. He says:

Maybe the reason I am so excited about the whole subject of Virtual Worlds is that in our own way we are beginning to have tools that let us make real the fruits of our imagination.

Just as word processors plus blogs empower our use of words, and digital cameras plus Flickr empower our use of images, creation tools plus virtual worlds empower our use of imagination.
