Please don't post multiple renderings of the same thing. Just the flat version is fine...don't need to see it on the office wall or anything like that.

A few more ideas that may work:

1. The text 'DIRTY STACK' but make the letter I a stack of chips (with the odd chip of course)

2. Have the text:

DIRTY
STACK

but render the letters as though they are all a stack of chips (again with an odd chip)
