Wrapping text around and filling text inside of shapes

[getsignups]

Ok please forgive my 'sketching' (I suck at it.)

1. As you see in the outside of the square sketch you see i have written the word "square". Its not so much about the square shape, but more so about the process /technique of taking text and having it wrap around any shape as illustrated.

2.Again, pardon the sketch. You see I have made a spiral shape. I want to have text start at a very minute dot and spiral out inside of a shape (not necessarily a square) and use repeated words/ text filling up the inside of whatever shape Ichoose.

Hopefully you understand my objective.

Thanks!
