I am not the best at math, or Geometry for that matter, so I could really relate to it. I really loved it and the twist at the end is just wonderful! It is a very short film, but it does not need to be a 3-hour lord of the rings movie. It's in Spanish with English subtitles. I saw the new 2010 version on the Blu-ray edition of Cronos. The song used for the end credits does not really fit the movie, but I really liked the effect it gave, which was similar to the end credits in Evil Dead. In an interview I watched before the film, Guillermo del Toro said that the use of magenta and dark blue colors really gave the film a nice effect. I can still remember watching the Dario Argento films like Susperia and Phenomena, and feeling that they had the same use of colors. The music in Geometria is very 1980's electronica with great use of synthesizers. I would rate the film a 10 out of 10. It's my favorite short foreign film.
