Nothing with CC0 projects specifically, but I've enjoyed buying merch and branded items like coffee blends that projects have made available for NFT holders. Getting physical prints of art NFTs is also something many people like to do. These IRL artifacts make the NFTs real in an interesting way.

At the general level, I think the potential uses for NFTs in creative ventures are limitless. Simply because NFTs themselves are just like a certificate of ownership over an asset, and there is simply no limit on what that asset could be - e.g. images, videos, music clips, writing, poetry, etc. ​ On this note, I guess what people can do with their NFTs would be no different from what they can do with other non-NFT creative assets, and much will depend on the copyright and usage rights assigned to the specific creative assets. Personally, I have plans to print out 1-2 of my NFT images to display at home. ​ More specifically, I guess people can also leverage on the unique, blockchain-based features of NFT for creative uses. For instance, imagine if a piece of NFT changes every time it gets transferred from one wallet to another - this could open up interesting uses with regard to generative art based upon blockchain data. Another key feature of NFTs I guess is their immutability. On this note, I'm planning to propose to my girlfriend soon, and I intend to complement this occasion by sending her an NFT that can commemorate this occasion on the blockchain permanently.
