First of all, I'd like to thank petelusk for suggesting this. I've started working on a spell bar that looks like a sword. This might be of interest to you melee hybrid casters.
I've mostly got the graphical work done, but I've still got to code and arrange it. If I keep at it I might have it released by tonight, although I doubt that.
And here's a screenie:
This graphic was done completely from scratch using Paint Shop Pro 8.
UPDATE:
The sword spell bar is now in game and almost finished. Here is another screenie:
It seems more or less in-tact, if somewhat granulated. I still need to make a spell-book button as you can tell. I also noticed that the sword is somewhat bright, so I am going to make a dark variation. I'll most likely package them together for convenience and upload them when I'm done. It should be done today if I don't have too many distractions.
