The dots in the logo have a hidden meaning, it is 502 written in binary code. This is an alternative way to write 502 - other than all the others - more modern :)
Clever with the binary code! A truly unique approach which I respect.
I like the idea with #109 - I just worry that the 502 doesn't sit by itself very well... Many times our clients refer to us as simply "502" and the omit "media group". We have often done promo stuff with just 502 being our logo. I worry that the 502 might be a bit hard to decipher if you didn't already know the name of our company and we're seeing the logo for the first time.
