What's the purpose? Like, what are my votes to be based on? FaceMash was based on hotness, or something. What is this? I see a picture of a C3-P0 helmet versus a picture of a VoIP phone. Am I supposed to just vote for the picture that somehow touches me the most?
Yep. Nothing too serious, just some fun; which ever one is more visually appealing to you, or (as you say) touches you the most. It will be interesting to see which pics rise to the top this way.
It might be good to state that somewhere. When I looked at the site I felt like I was being called on to answer a question, but I couldn't figure out what it was. Led me to skip a lot of comparisons. Once I decided it didn't really matter it was a lot more relaxing.
I think a little more instruction to the user would be helpful. I kept picking which picture I would rather be in a fight against until I came here and read the comments.
