Helium can lift approximately 65lb. per 1000 cubic ft. from the images in the video, the balloon was no more than 12ft in diameter, or approximately 900 cubic feet. The boy, the balloon, and all the equipment can’t weigh less than 65lbs. Next time you want to wast millions of public money, do the math first.

The mutoscope running for real!
Some photos of the mutoscope from the last week. It runs, it projects! Everything needs to be tightened up (and quite a bit re-built) so it can be shipped, installed, cranked by museum goers, broken down, repeat x4. But after 3 months of work I have an amazing lightness of being- something like, “oh, I’m not full of shit.”
Using columns to manipulate user behavior
web activist aaron swartz’s blog uses two columns that are left and right aligned. in a large browser window they open a gaping hole in the middle of the page.
When I browsed to his site my first instinct was to shrink my window down to about 700 pixels wide. at it’s minimum size, I believe (but can’t verify) that the site is exactly a sideways fullscreen iphone.

6 weeks, 480 frames: a mutoscope cartridge
Where I’ve been the last six weeks is cartridge land. Lots of production problems. For the hub I had to switch from lathe/cnc to stereolithography, and the polystyrene (generic .015″ plasticard) had processing problems that the printer had to work out (beautiful now). Mounting the cards into the hub took several tries as well… Big gallery here, a gallery where I’ll be collecting a lot more work soon (2008 WSCCPR videos will be back up Real Soon Now).
The next step is to attach the finished projector to the player with speedrail.
