Just spotted this trailer project:

Not finished, and seems a tad expensive, but might provide a few ideas...

Oh my god! That firefox thing is even uglier than I thought! I had never seen it from the rear! Kill it! Kill it with fire!

Beauty is it the eye of the beholder.....But yes its pig ugly. And a tad front heavy by the look of it.

oh bleep ... that was ugly


no no not ugly... disgusting
