creative ambient ads

i found this ads from the internet,




i really like this ad, because if the sun isn't there, then the writing doesn't make sense at all, but when the sun is up, you can read the shadows, which said

"take a break from the sun"


it would be funnier if it said

"if you can read this, then u need a break from the sun"


but i imagine that this would need more space

anyway this is actually an ad for "Peter MacCallum Cancer Center"

so 2 thumbs up!
