I've been playing some more with the same time same direction patterns Yuta was showing off at Firedrums and trying to apply the concept to stacking patterns. While technically none of these are true stacks, they share some similarities in concept in how the hands change orientation in relation to each other. Going a bit down the rabbit-hole, here is a pattern that essentially amounts to performing a stack in all four directions and alternating between an antispin and extension transition to do it.

After posting tech blog #71, I realized I could easily take the top stall that was giving me so many problems and use it to transition into the pendulum stall down maneuver I already had down to create kind of a funky waterfall effect. As was pointed out in comments, this move also provides an excellent point of entry for Ronan's pendulum stall stacking move from BJC--that transition is demoed here as well.
