There was a great Love/Hate one a while back, and
I remember seeing it on (or at least via) Typophile.

Oh, nice one. ;-)
The love/hate one is here (for example):

Yeah, that image was definitely the inspiration.

I do like it, but I had trouble reading them, especially 'go 2 hell'.

Cool, but difficult to read mission failed.

"I had trouble reading them, especially ’go 2 hell’"
Interesting – that one was much easier to read for me. I mostly have problems with that "b" ("B"?) in "no prob".
But all in all it's very fitting for certain job situations. :->

Yeah, I will agree that it is difficult to read. I guess if I ever made the shirt it would be more of an inside joke, only you're the only one in the loop...

And showing it to a few people, I've had people say "go 2 hew" and "no prog". Everyone is reading it quite different, as expected. It's not that big of a deal if it's a lost cause, but any comments on how to improve the legibility, without recycling the celtic style you see in a lot of ambigrams?

Thanks for the input, all.
