Haha thanks man I try to help out where I can - I too was inspired by www.teamwizzy.com back before WoW was released.

I have no problems casting Flamestrike / Blizzard but I generally choose not to in most situations.

To do it - you need 4 wireless mice. Set them to the same frequency so they are all in sync. They obviously need to be the same brand and the same model to ensure it will work.

An aside: the mice actually will drift some due to EM interference and other things that would be quite difficult to avoid (unless you want to build a rather large faraday cage) even then I am not sure you could completely correct for it without some additional hardware. This is with IDENTICAL hardware - with dissimilar systems... good luck on that

It works well enough for a little while and then you just need to resync it by moving the mouse to the corner of the screen. I assume you could figure out a way to program a mod to move the cursor to the EXACT center of your screen but the corner works just as well.

Anyway - sync up the mice and /follow one of your characters. This lines up the view points. Hit your "blizzard" macro and then move the single mouse to where you want to target. Click once and its a snow storm
