These “clouds” or “thought bubbles” are stationed along the exit of Denver International Airport in Colorado, USA. These have the potential to be really cool signs and make people think about….SOMETHING. But they are blank. Empty. Random.
The State of Colorado or City of Denver could easily use them as marketing tools. For example: Cloud #1: It may be really flat right here… Cloud #2: But just wait…Cloud #3: We do have mountains, seriously.”
