speech bubbles

I was thinking about how interesting it was that different lines and symbols could be used within comics and cartoons to represent things that it would otherwise be difficult to convey. Some examples are, A circular bubble to show what someone is saying. A cloud-like thought bubble to show what they are thinking. Wavy lines over something to show it has an odor. Straight lines behind something to show it is going fast. etc. I was wondering how hard it would be and over what period of time it would take to implant new comic features into society. I have some ideas for a few this is just one, the aural bubble showing what people are hearing. The actual design of it needs works but I like the idea at its core.

Rainy Days, Rainy Days

Hey. It's nice when it rains because it is like a shower for the city. Imagine trying to get the amount of washing done in the city that the rain accomplishes it would be really expensive. It is like putting Chicago in a giant dishwasher.
It would be great if we created more ways to take advantage of the amazing power of the rain and all that free water. Also it would be cool if the city was designed to change the functionality of the public areas when it rained. The streets could be canals and the parks could be ponds and the building tops could be swimming pools.
