Alright, here's what I got jumping onto the transparent unit frame bandwagon
First shot has battlefield minimap up; I use it a lot for gathering/exploring, but I'll probably turn it off if I'm just questing. Second gives an idea of what it looks like in raid, and third is... well possibly a very silly idea, lol. It's been working out for me so far; I could never use it in a raid or any situation where I actually care about the names and exact percentages, but for mass random battlegrounds I think I like it. And the action bar in the corner was made visible primarily for alt-leveling purposes.
I'm undecided if I should add more of the gradient panels around things (like the friends/guild brokers at the top).
