Shia was visiting the Factory of the Sun exhibit by Hito Steyerl when he decided to start dancing around like a maniac. According to another visitor there last week, the exhibit is a 23-minute video meant to be enjoyed while relaxing in lounge chairs. As he tends to, Shia took his own approach ... with a friend.

We're told Shia was part of another project at Kiasma called Alone Together ... which involved live streaming from a remote cabin in Finland to a cabin inside the museum.

Looks like his desire to dance was more alluring.
