So I finally found out how to get the binary array extension working. But I believe I also found a bug with the extension. The file below crashes when run because of the "set virtual size" action. If you change the properties of the extension to something along the lines of: size = 100, width = 10 and height = 10 it does not crash. Not a big deal, but I thought I might as well let people know that it does.
(Also, some documentation would be nice :P)
