I need help coming up with a project idea to create an Ethereum Dapp. Here is the project:

For your project you should design and implement an Ethereum Dapp. Your Dapp should include:

at least one smart contract

capable of being deployed to the Rinkeby test network (even if you choose to test it with Ganache-CLI for ease of development)

software to interact with the smart contract:

EITHER command-line Node.js program(s) using Web3;

OR HTML/JS interface (like simplecoin.html and simplecoin.js)

PLEASE SHARE SIMPLE DAPPS I CAN CREATE
