Xalos' elevator mod.
I tried it but there's a couple problems:
1. Only one color (boring grey)
2. Is not flat (minimum of like 2 bricks in between platforms)
However, I do like that it has adjustable speeds, sizes and shapes (sorta). If I could make a clear version or vertical version (1x8x10) I'd be really happy.
This video shows the Xalos' elevator mod used as a moving platform.
