It's probably time to do an overhaul on the smilies again. I went through and cleaned up a ton of them a few years back when we moved the forum to runboard and tried to make as many as I could visually consistent. We were using the default runboard emoticons and the ancient RPF traditional emoticons didn't match so I recreated them to match. (I swear I spent at least 6 hours to get that frakking rolling/laughing smiley to animate right at the time...)
I always say this but I've been wanting to do some new themes too for a long time but family and work keep getting in the way of my pet projects If I could only get paid for doing that kind of stuff :lol
