Pong – a grid contra

This is a follow-up to the grid contra I wrote earlier. I think it’s more danceable, and traces patterns that are more fun on the floor. I’ve changed from Bias/Other to colors to describe the corners.

Pong (Grid Contra)

single set lateral progression (i.e. double horizontal becket)
single vertical progression
Alternating Left or Right designation for sets
Orange corners:
for left sets is gents (people on left); for right sets is ladies (people on right)
Purple corners:
for left sets is ladies (people on right); for right sets is gents (people on left)

A1 ———–

(4) Balance the Ring

(4) Orange corners swap by right shoulder, all face across at neighbor

(4) walk across set to new set, Pass neighbor 1 by left and neighbor 2 by right

(4) Women allemande left half way

A2 ———–

(16) Neighbor balance and swing

B1 ———–

(8) Circle Left 3/4

(8) Partner swing

B2 ———–

(4) Balance the Ring

(4) Purple corners swap by right

(4) Right to partner, balance

(4) square through: pull by right with partner and left with neighbor – face new neighbor

Notes:
When you reach an edge of the sets, you pass your partner (as neighbor #2) and face back in. Your corner color swaps purple<->orange.
When you reach an end of a set, you wait out one time (and swap places with your partner). Your number changes 1<->2, and your color changes purple<->orange.
In either edge or end case, you’ll “bounce”. You change one direction of travel, but not the other one. Your color swaps when you wait out one time at the ends, but the lateral wall you’re travelling towards doesn’t change.
As a mnemonic, O comes become P, so the Orange corners will swap before the Purple corners. Orange corners are the folks standing on the direction of lateral progression side of their couple (i.e. gents are on the left, so left sets have gents as orange couples).
Tracing through the moves:
For a 3 set group with 4 couples in each set, we’ll initially designate the edge sets as left, and the middle set as right.
Orange corners are A#m#, B#w#, C#m#
 
    L          R          L
A1w1 A1m1  B1w1 B1m1  C1w1 C1m1
A2m2 A2w2  B2m2 B2w2  C2m2 C2w2
 
A3w1 A3m1  B3w1 B3m1  C3w1 C3m1
A4m2 A4w2  B4m2 B4w2  C4m2 C4w2
 
 
A1 ———–
(4) Balance the Ring
(4) Orange corners swap by left shoulder, all face across at neighbor
Initial orange corners are A#m1 & A#m2, B#w1 & B#w2, C#m1 & C#m2
 
 
    L          R          L
A1w1 A2m2  B2w2 B1m1  C1w1 C2m2

A3w1 A4m2  B4w2 B3m1  C3w1 C4m2
A3m1 A4w2  B4m2 B3w1  C3m1 C4w2
 
(4) walk across set to new set, Pass neighbor 1 by left and neighbor 2 by right
Note: at the edges, pass your partner and face back in
 
    R          L          R
A2w2 B1m1  A1w1 C2m2  B2w2 C1m1 
A2m2 B1w1  A1m1 C2w2  B2m2 C1w1
 
A4w2 B3m1  A3w1 C4m2  B4w2 C3m1 
A4m2 B3w1  A3m1 C4w2  B4m2 C3w1
 
The columns have now swapped, the edge columns are “Right”, and the middle column is now a “Left” column. Looking at the top two rows of couples: A1m&w1 & C2m&w2 kept their Left designation. B1&2m&w1&2 all kept their Right designation. A2m&w2 and C1m&w1 bounced off an edge and switched from Left to Right; and so their purple/orange status switch.
(4) Women allemande left half way

(4) Purple corners swap by left
Initial Orange corners were A# m1 & m2, B# w1 & w2, C# m1 & m2
However, current “Purple corners” are, for the top two rows: A2m2 & B1m1, A1w1 & C2w2, B2m2 & C1m1
where A2m2 and C1m1 swapped their corner status when they bounces off the edge.

So now we’ve gone through the dance once.

(4) Orange corners swap by left shoulder, all face across at neighbor
Current Orange corners: B1w1 & A4w2, A1m1 & C4m2, C1w1 & B4w2

(4) walk across set to new set, Pass neighbor 1 by left and neighbor 2 by right

Note, even though the couples out at the top and bottom haven’t done anything, their columns just swapped from Left to Right, and vice versa.

B2 ———–
(4) Balance the Ring
(4) Purple corners swap by right
Orange corners at beginning of this time through: B1w1 & A4w2, A1m1 & C4m2, C1w1 & B4w2
Current Purple corners: B1w1 & C4w2, A4m2 & C1m1, A1w1 & B4w2 (bolds had an edge swap)
 
    L          R          L
A2m2 A2w2  C2m2 C2w2  B2m2 B2w2  – OUT
 
B1m1 B1w1  C1m1 C1w1  A1m1 A1w1
c4w2 C4m2  A4w2 A4m2  B4w2 B4m2
 
B3w1 B3m1  A3w1 A3m1  C3w1 C3m1  – OUT
 
(4) Right to partner, balance
(4) square through: pull by right with partner and left with neighbor – face new neighbor
The out couples have swapped with each other, and come in as 1s or 2s
 
    L          R          L
A2w1 A2m1  C2w1 C2m1  B2w1 B2m1
C4m2 C4w2  A4m2 A4w2  B4m2 B4w2
 
B1w1 B1m1  C1w1 C1m1  A1w1 A1m
B3m2 B3w2  A3m2 A3w2  C3m2 C3w2  
 
That’s twice through the dance. 
After the next time, we’d end up with:
 
R   L   R
C4  B4  A4 – OUT
 
C2  A2  B2
B3  D3  A3
 
C1  B1  A1  -OUT
 
And then the next time:
L   R   L
C4  B4  A4
D3  B3  A3
 
C2  B2  A2
C1  B1  A1
 
So while A1 & 4 and C1 & 4 are bouncing back in forth in the big set diagonal, B1 and B4 are actually tracing diamonds. The patterns are limited by the small set size that I felt like writing out; but I think it should scale; technically from 1 set (which would be awkward, and only one person in each couple would get to be a corner the whole way down) to any number across and down. 
Feel free to send me questions.
