A little something I tried experimenting with. I found a Rin and Len track of The Lost One's Weeping. In addition to having them play on top of each other in both speakers, Len is also coming out of the left and Rin out of the right speaker at the same time.
Additionally, there are three layers of videos. A solid Len layer is moved 25% to the left, a solid Rin layer is under that 25% to the right, and a transparent Rin layer on the very top also 25% to the right. This has the effect of making it look like they're both on stage (and the unremovable transparency in the middle). There is some weirdness with the spacing, but I overall like the results.
