Mat for Magic Trackpad 2

I like Apple Magic Trackpad 2, except one thing: the slope of its surface. I prefer the using experience of the touchpad on MBP, whose surface is parallel with the desktop. I think that gives the more natural feeling when you touch something laying on the desktop, since you can move your fingers on the touch pad without sensing that the height of the surface which your are touching keeps changing with the movement.
I think this sense is subconscious, but you just know it and when they kept coming into your brain when you are woking, it is annoying.
So I made this mat for the Apple Magic Trackpad 2, it does only one thing: making the surface (almost) parallel to the desktop.

Since I want it looks harmonious with the Magic Trackpad 2, I made it looks like a dialog bubble when you put it under the Magic Trackpad 2.
(Actually, since the surface is made of glass, you can "say" something with this dialog bubble and dip some alcohol with tissue paper to erase)
