** Project plan

- [ ] Order Wiimotes/ir cameras
- [ ] Decide whether accelerometers are necessary.
- [ ] Design a circuit to read ir/position data.
- [ ] Figure out how to transmit ir data to the computer. (I think
  wiimote uses I2C)
- [ ] Determine how to read incoming data from a javascript
  application (maybe via nodejs)
- [ ] Design a head mount for led lights, e.g. by printing.
- [ ] Decide whether to use two three or four lights.
- [ ] Decide on whether to use a tetrahedral light arrangement
- [ ] Build a simulated environment.
- [ ] Enable reasonable programmatic movement of the simulated camera.
- [ ] Interface the simulated camera with the incoming data

- [ ] Wiimotes use bluetooth to connect. This is how the nodejs wii
  program does it. A program like BlueZ is required to add bluetooth
  functionality on linux.

  - In the i2c protocol, SCL refers to clock signal and SDA refers to
    data line. See Neil's examples: http://academy.cba.mit.edu/classes/networking_communications/index.html
  - In I2C, every object has a 1-byte I2C address apparently. The top
    seven bits are the actual address, and the final bit is used to
    declare r/w mode.
