A brief browsing of Motion Labs' website leads me to believe they don't make a specifc "cue light" system (which would make sense as I don't believe this would be terribly profitable). Many of their products are geared towards
power distribution systems. The "remotes" section of the website lists remotes to control their chain hoist/automation products. My assumption would be these remotes would not work for the power distribution systems.
The shows you mentioned are obviously very large scale shows. If they were using "Motion Labs" products my guess is they were using a large distributed power system to control all of the show lighting, with perhaps a few circuits set aside for the SM's cue lighting system.
Noting the experience level you have listed in your profile as "high school" I assume something like this would be well out of your budget (not to mention likely overkill for your production's technical needs). You may look at something like their
Rac Pac (1100-1-W-W-01) product. This is a 1RU small scale power distribution unit with six independently switched power outputs. At less than 4" deep it's extremely shallow and could easily be mounted in a rack within arm's reach or right at the SM's calling desk.
