Some have built portable setups with an Indy and an Indy presenter. I remember 25 years ago someone showing off with such a custom portable configuration, with an Indy motherboard and PSU, a keyboard and track ball and an Indy presenter crammed inside a small metal suitcase, very chic (but required external power).

Fake versions were made for the movies "Twister" and "Congo" but AFAIK these were completely fake (the actual Indy driving the screen was off camera somewhere).
