That was fun :)
opal1159 mentioned it on #lj_support and I had the idea to steal her icon.
A little bit of wrestling with Paint Shop Pro (and a chat with Opal on AIM to ask permission) later, I had a new icon, which I made my default for about a week.
It was fun to see it confusing other support volunteers (especially in one request where there were two very similar icons one right beneath the other [I2 in comms required, or see a screenshot]). It was also kind of fun to see it confusing me—for example, when reloading a support request I had just commented on and thinking that Opal had been quicker than I.
But I think that was enough fun for now. I'll keep the icon around for the time being but it's no longer my default.
