There are 3 main ideas behind a Micro Theater:

1. Portable: You can take it with you (outdoor movie parties, camping, drive-in movies, etc.)
2. Small spaces: Doesn't required a dedicated room & can be used in bedrooms, dorm rooms, half-finished basements, garages, etc.
3. Low-cost: Between $350 to $1000 (depending on your requirements)
