Get ready for the Great American Solar Eclipse with this Heptapod shirt! This design imitates the "diamond ring" effect sometimes observed on solar eclipses, with a Heptapod logogram taking the place of the light from the sun. (This particular logogram is the word for "life," according to my sources)
A heptapod logogram from Arrival with an integrated strand of DNA. In other words, two universal languages! The heptapod itself doesn't mean anything; it's just a design done in the style of the movie.
A depiction of the incredible newly discovered TRAPPIST-1 exoplanet system, with SEVEN earth-sized planets! In Circular Gallifreyan, the star says "TRAPPIST 1," and the star and all the planets (although they're difficult to see here as they are to scale) have the letters a to h on them also in Gallifreyan.
