Project Self-Critique - group project

I meant to do this yesterday, but in any case I'm going to be doing a review on the group project I was in. Our final project was a lineup of 5 black silhouettes marked with racial labels, with instructions on the side and a banner below that contained a quote (that I unfortunately don't remember very well. It got stolen, too!). We had originally only put a very small amount of racist stereotypes on the silhouettes, which in turn prompted people to write their own thoughts and ideas. We actually got quite an impressive response - I honestly didn't think so many people would have responded over the weekend, mainly due to the lack of classes. But people responded, and quite wonderfully! We had a few written responses that said some negative things, but for the most part there was an overwhelming desire for people to list the positives of the races, not to list stereotypes and negativity!
If there was one thing we could have done better, it would be to have both protected it from the rain, and to have had it up even longer than two days. I can't even begin to think about how many people may or may not have responded if we had left it up for over a week - the results would have been fantastic!
