A phase shift oscillator, courtesy of the Magnavibe. While it's not as powerful or as sophisticated as the Tremulus Lune oscillator, it's a much easier build and provides the needed controls to drive a lot of LDR circuits. "Depth" controls the brightness of the LED, whilst "Speed" controls the rate between fading on and off. I've also made another version of this circuit that allows for much slower speeds and will post it separately. At one point I made a "compact" layout of this circuit but it wasn't that much smaller and looked a little untidy, but if space is a concern you could shave off a couple rows and columns if you wanted.
