I don't know much about this tool, but if it's anything like the emblems in Halo, it's impressive that you were able to create this from a limited number of options.

It's more like the livery editor from Forza. Except more limited than that. Layers, transparency, colours, size, position, shape etc.

I was able to fairly quick knock up a facsimile of my Halo emblem in it. With my noob level art skills.

EDIT: BTW cheapLEY, thanks for bringing it to my attention! I wouldn't have known about it otherwise.
