This YouTube video describes the design and construction of a DIY ovenised voltage reference.

I have been pondering on the same idea. Using a low power resonant circuit for the deflection coils and wondered about Lissajous scanning. Found these interesting papers. https://www.mdpi.com/2072-666X/10/1/67/htm Scanning MEMS Mirror for High Definition and High Frame Rate Lissajous Patterns...

Here is a interesting report from GE in 1957 describing in detain the past and projected developments that were undertaken to reduce the depth of tubes as the size goals kept climbing. In the end a CRT was limited by physical constraints and the largest CRT displays moved to projection systems...
