Identities: Feedback

Before I start any real design work I want to find out what sorts of images work best. What does the eye find most appealing, a square or a circle?
The following test is potentially the answer to that question. I'll attach it to a revised version of the questionaire I showed earlier in the journal and get on the streets to score the feedback.
Help me with my studies and take my 'most pleasing shape' test. View the test and leave a comment on this post. Leave the number relating to the shape you prefer along with any other thoughts you have.
