Random late-night brainstorming

• Angle measurement (as mentioned elsewhere). Converging lines to eye at edge of screen. Surveying demo. Some simple reduction software. Couple of kids could survey room, field, get size info, build 3D model, etc, very quickly. todo: see if i can get hands-on a laptop for a couple of minutes to get a feel. Oooo, camera as high precision angle measurement tool? have textures ready for 3d then too.
• Timer. Beep a second, 10 sec different one, etc. Measure velocity, etc.
• Order of magnitude feel for numbers. 200 dpi means lots of dots. 100 distinct dpi? Slider, exponential, 1 to say 100,000.
  • Fractions. Big square. 1. down to 1/100000.
  • Combined range. 1 is 1in or 1/2in.
  • Circle graph. Colaborative slicing, each kids controls a slice, excess region for leftover. Or break apart/reasemble?

What infrastruct exists for distributed dynamic ui?

• Mouse runs from machine to machine. Hiding, appearing. Fur can be painted. Whose machine is it on? Carry messages?

In general, what infrastruct for graphical agents moving between machines? Animals, numbers, etc.

• Painting with sound effects is apparently very popular. Paint activity have sound? Stamps, etc. Add? Sharing custom stamps as community activity. Saving also key. Art gallery app?
• How much parallax is needed to do cloud height measurement? Velocity.
• "Appropriate tech" build-it receipies? barometer (thread), humidity, ...?
  • water droplet magnifying glass
• big picture
  • ephemeris. orient laptop by sun. hold laptop in orthogonal positions (up, down, left, right, etc) - see through earth, solar sys, etc.

enough computes for simple 3d astro syms? ss, local stars, galaxy. at least pretty rotating anims of each.

angle measurement + solar system model + sky observation + model solar system school yard

• • see through earth could be a neat demo. can use camera as horizon sensor?
• what is the state of doing fermi questions with <5th graders?
• camera edge detection (w+w/o multiple machines) -> good model formation? (3d, velocity, position, etc). anything cheap enough? just how much computes do we have?
• nonmesh communication protocols. sound, light. interesting collaborative hackability?
