So I’m zoning out in a subway dreary, and I see an ad with a kid looking through a gang sign. I look closer and lo, it’s an ad for some lame film school.

The kid is framing his hands in a type of 12:9 ratio (?) that you always see directors and cinematographers doing on set as they talk earnestly.  
[The subject could make use of the masterful study of hand proportions](http://www.google.com/imgres?q=durer+hand+proportions&um=1&hl=en&client=safari&sa=N&tbo=d&tbm=isch&tbnid=CsA429h0Ds_loM:&imgrefurl=http://www.1st-art-gallery.com/Albrecht-Durer/Hand.html&docid=fG_-1zr6PQ2ETM&w=600&h=374&ei=p51ETqWaIoGhtwfbxpHTBQ&zoom=1&biw=1024&bih=690) by Albrecht Durer (1471-1528).

The goal is to find out if any other animal could frame a scene.

I do not need answer fast. I don’t really even _need_ an answer at all, come to think of it.
