Screen Edge Flash Command

[:1]Hi Folks

I am new to these forums and am about to start writing my first addon fro WoW.

I am a sufferer of RSI/OOS what ever you want to call it and I find that when gaming I forget to stop and stretch regularly, so my idea is to build an alert system to remind myself when to do this.

I want it to be obvious but not intrusive, so I initially want it to pop a written message and have the edge of the screen to flash a couple of times. The issue I currently have is knowing what the commands are called, specifically the one that makes the edge of the screen flash.

Can any one help with what this is called.

Cheers

G|||Can you not use the in-game timer/alarm clock?

or the addon WoWtimer (http://wowui.incgamers.com/?p=mod&m=4225)? It may still work.|||Thanks Erinion, I will check out WoWtimer, but I would prefer something that is less intrusive, I don't want to click something to reset it, I just want a reminder. That way if I am in the middle of killing a mob I can wait until I have finished, or building it to check if I am in combat, if i am then it delays for 20 seconds or something.

I was also going to develop a setting so if I am in a instance then it is disabled.

Any other suggestions are greatly appreciated.

Cheers
