I also though about the cut conjunction, but it's not so easy.
I made as far as this cubersome zigzag using transpose
|:,./('';1) ]`|.;.1 |:i.5 6
0 1 2 3 4 5
11 10 9 8 7 6
12 13 14 15 16 17
23 22 21 20 19 18
24 25 26 27 28 29
I was hoping this would work
1 (<`(<@|.));._3 i.5 6
|nonce error
| 1 (<`(<@|.));._3 i.5 6
1 <;._3 i.5 6
+-----------------+
|0 1 2 3 4 5 |
+-----------------+
|6 7 8 9 10 11 |
+-----------------+
|12 13 14 15 16 17|
+-----------------+
|18 19 20 21 22 23|
+-----------------+
|24 25 26 27 28 29|
+-----------------+
