left hand -v- right hand

I wonder if they make cameras for left handed people?, I am left handed when it comes to writing, you know the sort of writing that requires a pen or a pencil, but I seem to use my right hand for most other things. I can't for instance use scissors in my left hand, (my mother could) I can not use the mouse in my left hand, my brain just won't send the right messages at all even when I used someone else's mouse that had been configured to work that way. So how can I take a photo of my right hand on my mouse - with great difficulty. First of all my sleeve kept getting in the way, then my finger would reach the button and hold the camera straight, I suppose it might have been ok if I had turned the camera up side down (didn't think to try that). As you can see I did eventually manage to get the shot.

Why should I want to take a photo of my hand on the mouse, well I was reading Amy's Blog and as you can see (if you click the link) she has taken a photo of her red shoes on her feet, I like that idea but I mustn't keep copying other people must I? so chose my hand instead.
