Fixed Axle Rebirth?

It seems like fixed axle yo-yo play went relatively unchanged for about 50 plus years, has it recently been reinvented? The demonstrators from the fixed axle era were amazingly talented, but was there even a hint of the potential for fixed play in the tricks and performances from the past?

I would imagine a lot of the demonstrators had some tricks that never got circulated around because nobody else could do them. It really makes me wonder.
