If the laptops run Windows between 95 and 7, then there's likely a lot of JScript and JavaScript running in things like Active Desktop, desktop widgets, possibly startup scripts and obviously inside IE. I'm not sure if all this stuff is still around in Win8+ though.

Also, please don't give them any ideas. It's enough that every other JS webdev company uses rocket-related imagery on their site, we don't want them to design actual rockets.
