This circuit fun video presents the Twin-Tee op amp oscillator - a fun circuit that can make low distortion (low THD) sine waves with simple resistors and capacitors, no inductors. It is a circuit you don't see written up too much.

Here is a link to the Texas Instruments article shown in the video:
