- Scale factor?
- Increases the length and height of the "ramp"
- 1 is a bump, 4 starts breaking textures, 6 is huge vertical wall
- Angle?
- Lower is flatter, higher becomes trapezoid with longer top
- ?
- Timing group
- With otherwise identical config, two bumps with same number move together, with 1 and 2 move oppositely

Effects
Bonus 7
- Swapping yaw and pitch: loop
- Swapping yaw and roll: twisting line
- Swapping yaw and pitch, roll 90.00000: vertical ring to the left
- Negative yaw: turnright
