But minor glitch: The dominos randomly fail to fall down. It happens sometimes around 20 meters, or 40 meters, or 50 meters. I haven't yet figured out what causes this, or how to prevent it.
When I first fired the laser, I thought "So.... what's the big deal?". But then I created a large box as a target and fired the laser at it. NOW I see what it's supposed to do! VERY NICE EFFECT!
Suggestion: Change "maxRays" in the laser from 1000 to 1. That way, it will not reflect off the target and burn the laser stand!
Um, sorry, but this isn't very good. The cursor flies around like a helium balloon! Very poor control. There are a lot of other etch-a-sketch scenes on Algobox, so you can take a look at how they did it to get some ideas.
Suggestion: Do not post comments in the scene title! Give the scene a descriptive name and post things like "hope you like it" in the Description section of the scene.
HOW does this scene work? You give no description how to use it! Keyboard keys? Mouse? WHAT???
EDIT - I found your description of the controls in the original version of this scene! NOT GOOD! You should show the controls IN THE SCENE so that people know how to use the scene without having to figure out that the description was posted 3 or 4 versions ago! Older versions get buried sometimes 3 or 4 pages deep.
Suggestion: When clicking on the axle, it's not apparent if the steering is on or off. Might be nice to have some sort of indicator, such as a change in color, etc.
