I was a huge fan of the concept (time slicing LUTs). The name "Space-Time" actually made sense. Unfortunately, mapping designs to regular FPGA fabric is already hard and it apparently was too difficult for the Space-Time fabric and thus they folded. There are a lot of open FPGA efforts around. I hope someone else gives the idea another shot. While we are on exotic approaches, Achronix' first generation was using an asynchronous (1 GHz) fabric. I regret I didn't get a chance to play with that before the pivoted to a conventional fabric.
