Real Time Chess – A physical chess board without the concept of turns

There was a demo from around 5+ years ago of a experimental real-time Chess board which looked remarkably similar. Once a piece was moved, a visible circular timer with a duration proportional to the piece valuation would count down until they were allowed to move the piece again.

I wish I could find the link but trying to search YT for relevant results older than a couple years is just trash.

Could it be the Kung Fu Chess games mentioned in the video?
