Let 0,1,2,3 be the four mobile 2x1x1 blocks, numbered by elevation
Let 'u' be the direction that the 0 block can initially move
Orienting such that 'u' is up, let 'l' be left, 'd' be down, 'r' be
right

I like the rolling block maze format quite a bit, and it seems to be
evolving rapidly. Again, this is the best rolling block puzzle yet.
From Joseph DeVincentis:
I'm calling the blocks 0, 1, 2, and 3 based on
how far they are off the ground, and north is the side the multi-color
block (3) starts near. I've provided descriptions of where 0
goes
since it moves so much, in case I've messed up somewhere.
Move 0 so it is S of the block 1 is on. (NENWNWWWSWSSSE)
1: SEN
0: WN
1: WSE
0: NE
1: NN
Move 0 so one end is in the cavity immediately S of 3. (WNENEEESSESWNW)
1: EES
2: ESW
1: NW
2: NES
1: W
Move 0 where it was just after "0: NE" above. (ESENWNNWWWSWSE)
1: WS
2: WNE
1: WS
Move 0 so it lies N-S, N of block 1. (WSSESWNNNE)
1: NNE
Move 0 so it stands on end in the cavity W of 2.
(WSSSENWNNNENEEEESWWNWWWSSSE)
2: WN
Move 0 so it stands on end in the cavity S of 3. (WNNNEEESEENWSSW)
2: ES
Move 0 so one end is in the cavity S of 3. (EENWSW)
1: E
3: SS
This is the end of the first major part. We have moved 3 over
into
the right neighborhood.
In the next part, we first have to undo the last set of moves of 1.
1: W
Move 0 where it was during "1: NNE" above. (ESENWNNWWWSWSSSESWNNNE)
1: WSS
Move 0 where it was after "0: NE" above. (WSSSENWNNE)
1: NEN
Move 0 so one end is in the cavity now N of 3. (WNENEEESSESWNW)
1: EESS
Move 0 around to the 2-space cavity S of all the other blocks.
(ESENWNNWWWSWSSSESEEN)
1: ESWN
Move 0 around so it lies E-W, E of 1's north end. (SWWNWNNNNEEEESWNESSSS)
1: EES
Move 0 back to the 2-space cavity. (NNNNWSENWWWWSSSSESEEN)
