Shia LaBeouf

Shia LaBeouf still isn’t famous, but he’s still doing weird things on the internet. Case in point: He’s spelling out something with his running routes using Nike+.

After a months-long hiatus (interrupted by a post of the actor pouring ice over himself for the ALS Ice Bucket Challenge), LaBeouf started tweeting fitness updates Monday. The first was nothing special—just an automated tweet from the Nike+ app reading, “I just ran 1.83 mi with Nike+.” The second was even less exciting, as he didn’t even break the one-mile mark: “I just ran 0.85 mi with Nike+.”

But click on the links in those tweets, and you can see LaBeouf’s exact running path. More importantly, you can see that on Sept. 3, that path looked like a hashtag and on Sept. 4, it takes on the form of the letter “M.” Is Shia trying to tell us something?

While “#M” doesn’t really provide many clues as to what LaBeouf’s final word/sentence/code will be, he could just be drumming up his upcoming movie, Fury. LaBeouf stars as a member of a tank crew in the World War II-set film and gives a performance that director David Ayer said will impress audiences. “He’s one of the best actors I’ve ever worked with,” Ayer told EW. “People are going to be shocked by how strong his performance is.”

Fury arrives in theaters Oct. 17. Updates on LaBeouf’s Nike+ message to come.
