todo

data formatter

1. Find interesting data sources
2. 1
3. 2
4. 3
5. Write code to fetch data from sources
6. Cache data
7. Layout data with canvas
8. Test functions with HTML5 canvas
9. Work out way of switching between data (in a pleasing manner)
10. Work on demo screens

canvas implementation

1. Implement functions using only lineTo
2. Test functions
3. Text generation
4. Black and white image drawing

arduino driver

1. Create Arduino protocol
2. Convert given points to 2D relative step array
3. Work on calibration routine to hardcode values
4. Pass values to the Arduino
5. Add checks to ensure values do not exceed bounds

arduino enacter

1. Move motors by given amount of steps
2. Implement Arduino protocol (relies on #1 of arduino driver)
