Tesla always had “light show” as a fun gimmick. It’s one of the first things you show friends and family.

There’s a few canned versions but apparently you can create your own on usb stick. Supposedly it was an outgrowth of qa, so it includes things like windows and trunk opening and closing, side mirrors folding and unfolding, all timed to music, etc. Even before the active matrix headlights were approved for regular use, one of the canned light shows used them to spell out “Tesla” on whatever is in front of you.

A recent update mentioned new light shows and a way to synchronize. I can certainly imagine a Tesla club having great fun with this
