I enjoy pressing buttons. Sometimes I press them in the right order to make LEDs do funky things.

Interactively experiment with timings of WS281x LEDs

	/*
	* @brief A tool to interactively experiment with timings of WS281x LEDs
	*
	* @warning Only one LED should be lit at any moment, BUT the nature of
	* overclocking means it's possible that all your LEDs will display full
	* intensity white light. This has happened to me several times already.
	* Be ready to unplug things. Ensure proper power supply and cooling.
	*
	* Connect using picocom, PuTTY or similar to adjust timings in real time.
	* Pressing 'o' will overclock all four timings by 1 tick (12.5ns).

Sub-pixel resolution is kinda essential for 16x16 displays.
