	It would make sense for Red to be 5V, Black to be Gnd, and the other two SCL and SDA of the i2c bus~~. This needs some further testing, preferably with a known good i2c device connected to the expansion port~~. The ~15kOhm between what I suspect to be SCL and SDA would then be two ~7.5kOhm to some common 5 V point that is buffered from the 'Red' cable.

			I did some further testing with a known good i2c device connected to the expansion port, but this just hung the i2c scanner or crashed Vortex depending on how I connected the port to the little display. Needs more work...

			Both pin 3 and 4 seem to be at +5V to the usb ground

	This sketch turns Vortex into an eggtimer to be used to keep track of how much time you have left when giving a talk, or before your food is ready. It displays the time left on the eyes, and can be controlled with a IR remote to (re)set the timer. LED colors are adjusted based on the time left, with vortex blinking red when you're out of time.		This sketch turns Vortex into an eggtimer to be used to keep track of how much time you have left when giving a talk, or before your food is ready. It displays the time left on the eyes, and can be controlled with a IR remote to (re)set the timer. LED colors are adjusted based on the time left, with vortex blinking red when you're out of time.

			Below the timer is set up to count minutes, but you can of course change the number of milliseconds per 'tick' to count seconds or whatever. Adding things like rotating lights to indicate progress of time or playing sound effects if desired are left to the reader, this is more or less a demo of using the eyes as a digit display.

			Because the two eyes are rotated 180 degrees compared to each other, there is code to swap bit-patterns (for the full 5 pixels per row, even if the digits here only use 3 per row). The font is rotated at run-time in setup(), so it's easier to tweak the font.

			Make sure to restart Vortex in time for the 55 day limit on the millis() roll-over not to affect things, or add code to detect and handle the rollover.

			The code to work with a remote is set up for a specific remote controller (RC 240 in TV mode), so you probably have to adjust this bit to work with the controller you intend to use.

	Looking at the connector from the back of Vortex:		Q: Does Vortex support sensor module expansion?
			A: Vortex has a “Maker mode” where you can connect sensors via its IIC/TWI interface.

			It would seem the only logical place for this is the 4 pin connector in the back. Looking at the connector from the back of Vortex:
