Future Life- bottle cap structure

For my future life project i would like to use bottle caps to form my structure but i'm not entirely sure how i want to go about it so need to do some experimentation...
Firstly, Here is the project brief that i have written for myself.

Thanks to a friend i luckily now have over 100 bottle caps to experiment with!...

Here is an initial idea of what i thought the structure could look like;

with the bottle caps stacked on top of eachother connected by wire in the centre a bit like this...

to then make something like this....

lots of which would turn into something like this....

An alternative would be to arrange the bottle caps side to side like this

They can be attached together using wire and wrapped around a free standing metal structure

Or some can be arranged to create a letter or shape....

all together it would look something like this...

making a structure looking similar to this...
