1. All neon tubes have small XPresso.

2. Material is switched.

3. Position of the neon to the "handle objects" is key to switch. "Neon_switch" changes position of ON state neons.

4. "Neon_switch_L" and "Neon_switch_R" changes range of ON state neons.

5. Next, you can change speed of neon flow, by user data "speed" of object "Neon_switch". Minus value changes direction of the flow. 0 stops the flow.

6. You can change ratio of ON state neons to OFF state neons, by userdata "threshold". 0 switchs ON all neons. and 100 switches OFF all neons.

7. You can change scale of the flow, by userdata "wave_length". Larger values get rough pitch of neons, and smaller values get fine pitch neons.
