HEAR YE HEAR YE: NERDIMPORTS HAS A COAT OF ARMS
I found a neat little website earlier today. You can make your own Coat of Arms. It is free and easy. So I made one for the website. It took me just a few minutes. There were many styles available.
I could definitely see this as a handy tool for roleplayers. Unfortunately, the image output is less than 432×446 pixels. The site’s owner should consider offering a premium option for a larger size–something that could go on posters or t-shirts.
