Here’s an interesting photograph:
I took the photo of my iBook using the iBook. By browsing to the webserver running on my phone. Which was pointing at the iBook. The phone, in turn, was getting its IP address, via Bluetooth, from the iBook. It all seems very symbiotic.
There is so much magic coming together to make this photo happen that it’s a miracle it all works: think “my blender talks my toaster into squeezing oranges for it.”
