D-Type Flip Flop using only NOR Gate

Simple adaptation of the DFF using just NOR Gates.

"D" is the Square Wave Source.
"E" is the 5V DC Source. 

If E=1, Q follows "D". 
If E=0, last state of "D" is stored,

This is possibly the simplest approach to understanding how memory works. Mostly the DFF is done with NAND Gates, however after searching for such a circuit using only NOR Gates returned nothing, I am now submitting this in hopes to fill that gap for the community.

Definitely a mind bender. Cleaver logic. An alternative circuit to the astable flip flop.
