Here's one of mine own 4x4s. I've posted it once before with different language, but I believe it's more clear now.
Mee Cro WAH Vay
By Jerome Grisanti
Four facing Four
A1: With facing couple, circle Left 3/4,
Opposite Neighbor swing.
A2: Rings of 4 balance, Pass the ocean*, Balance, Circulate the waves across the set.
B1: Balance, Circulate the waves across the set,** Balance, Swing Thru (in wave, allemande right halfway, centers allemande left halfway).
B2: Partners Balance and Swing.
(NOTE: Title is Italian pronunciation of "Microwave")
* At this point, there are now waves of four up & down hall. It's tempting to join hands with adjacent waves, but resist doing so until everyone understands the next figure (waves circulate).
** At this point, everyone should have crossed to opposite side of set.
