I'm not even going to try to explain dreamlines. Here is how they explain it:
"Dreamlines is a non-linear, interactive visual experience. The user enters one or more words that define the subject of a dream he would like to dream. The system looks in the Web for images related to those words, and takes them as input to generate an ambiguous painting, in perpetual change, where elements fuse into one another, in a process analogous to memory and free association."
Enter a "dream" keyword and watch the effect. It is pretty cool.
