Balls of Art

Balls of Art is an NFT collection that should serve as a basis to learn SVG-based, fully on-chain NFTs, and as a first step to start creating your own generative art NFTs. It shows in a clear, high-quality, yet simple way:

• How to structure an NFT project
• How to optimize for gas
• How (pseudo) randomness works and how to create it without using oracles
• How to draw simple SVGs
• How to start playing with SVG animation
• How to create a very simple generative art with all of the above.

Next steps for someone learning from this:

• Create a more complex generative art structure
• Take input from the user to create art with input as part of the equation
• Learn more complex SVG
• Add more animation
• Create a front-end and engaging minting page and process
• Create more art.

This project uses:

• Newest Solidity
• ERC721
• Gas optimizations
• Good-quality code, suitable for learning
• (Pseudo) randomization
• SVG drawing
• SVG animation
• Fully on-chain logic, metadata, and storage

Simple generative NFT art as an output.

Each NFT piece is a process of randomized:

• Background color
• Each ball's size
• Each ball's color
• Smiley ball location
