Maybe something interesting starting here, it's been dreamed up by Jeri Elsworth. It's obviously in early stages, so keep an eye on it to see what happens.

That is an excellent design by Wookie!I've thought of trying to make a sine wave generator with a 555, that would be a challenge. It would be similar to make a crystal oscillator with one.
Wookie showed me a circuit here I found extremely interesting. I've been puzzling for years to use the comparators for more than what the 555 uses them for. For example, a single chip (555) switching power supply, the 555 driving a power MOSFET. Haven't got a handle on it yet, but my little voice is telling me it is possible.
