Hi guys

Just a simple example of how we can make nice emotional OLED mouths for Otto with the new expansion.

You can see the proportion is quite ok, we can always put it higher or use a bigger OLED display

I am just using regular geometric shapes instead of bitmaps, in this easy way we could have less memory for nano and more control of the size (mouth opening), when combining it with the cool dfmini speech you guys made.

Let me know what you think.
