The Fourth Dimension is Time

Pretty scenic arrangements in cinematic work usually commit the crime of using two dimensions, color on the level of XX century painting. Some masters, a proto one being Da Vinci, went as far as three with shadows and doors. In fact, many of the seemingly two dimensional forms of the XX included a third in the form of what cinema now is beginning to discover as the fourth.

The fourth dimension is emotions.

You're welcome, spirit wonderers.
