Create beautiful demo examples for the major ICP use-cases

[lastmjs]

The examples/stable/demo directory is a bit scarce. Ideally we would have beautiful demos showing how to implement functionality for the major ICP use-cases (i.e. ckBTC, ckETH, etc).

Find out which use-cases are most sought-after or confusing, and implement some beautiful demos for them. These demos should be aimed at teaching and not at our own internal testing.

@lastmjs do you already have some important use cases in mind? WDYT about tweeting about this and ask users to provide their suggestions here?

also, do you think it makes sense to accept external contributions for this?

another option would be to just adapt existing examples to Azle 🤔
