well its not quite confusing.. kinda looked like a wierd marriage between strange and awesome.. =D
it was fun so im upvoting it anyway
the idea is your supposed to present something that looks like its going to be one thing.. but then its not what it seems to be..
so illusions..
as per my first example: a Bombay Duck is a kind of lizard 'something' wich is not a duck or a lizzard

one face or two..

not moving..

you get the idea

this tower for example is held up by string.. no pole is conected to another pole.. our minds struggle to make sense of holding up a tower of poles with only string.
