This led me on a one-hour Wikipedia detour and I now possess detailed development knowledge of Disney's Haunted Mansion theme park ride.

Seriously cool stuff.

He meant Wikipedia time. I've spent three hours reading Byzantine history and related articles in about an hour.

Check for yourself with a timer:

1) http://www.online-stopwatch.com/

2) http://en.wikipedia.org/wiki/Byzantine_Empire

go.

Doctorow's novel is amazing. It really inspired me to change the way I approach life and appreciate value. Plus, it is relatively short!

Basically, that book is to blame for me converting from a slacker to a hacker.

I can't wait for real animated holography to become available commercially. The static prints that Zebra Imaging makes are already incredible (full color, 90 degree viewing angle, etc) and the video footage of their live table prototype looks nuts, though it needs on the order of 100GBps of hogel data coming into the surface for 3x3ft image...

It's been on HN, but the same tech has been used extensively for a couple years now to produce Vocaloid concerts.

It really is quite amazing unless you're at a pretty significant angle to the screen, like in the nosebleed seats or to the extreme left/right.
