I think what has to be remembered is that this is a graphic that hasn't be done specifically
for a mug (is that right?).
Does the image wrap around so that the left and right edge join under the handle? Right-handed people will see "NANY 2009", Left-handed people will see "DonationCoder.com" as they are drinking
For mugs, the best placement for a message you want the drinker to see is on the left and/or right side (if the handle is the back). Maybe we need left/right handled mugs?
mouser has asked the critical question
: is the text the important bit? If it's not, maybe even rotating it through 90 degrees would help centre it on the side of the mug?
