How do you plan to make this into an art piece? You do not have any prove that you own the wallet, so you will be be able to claim ownership of any artpiece that can be made from it, if it can be done.

Sorry for your loss, but you should stop tracking the wallet now, it's not good for your mental health.

There can not be any creative thought about this that can be related to how you can retrieve your seed phrase or keys that can let you have access to your coins. Ones the seed phrase or the private key is not accessible again but lost, your coin has already been lost also.

Had similar taught, when op had said he lost the wallet and now it has become an interesting art piece. A lot of persons lost access to their wallets due to carelessness or environmental disasters. But the truth of the matter op is that, you cannot recover your lost wallets and by watching it's value increasing, you will only cause health issues for yourself. So just ignore that you ever own the wallets to avoid being in such situations. There's no going back now.

What digital artwork do you want from that inaccessible wallet? One thing you need to forget is that it's believed to be a mental health issue, I agree with others.

OP has .22 BTC bitcoin from $50 to now worth $13,900 means he has lost his seed and password for years maybe a decade?
I'm not sure he would remember the seed and password that he forgot long ago.

No need for worrying about my mental state. I am well aware that the funds are inaccessible without seed and password. I was just brainstorming and looking for input to learn of it is interesting to turn it into for example an nft or whatever because eventhough the btc can not be used, simply the fact that they are out of circulation may somewhat contributed to the hype and scarcity we see today. Again, just brainstorming but thought it could be an interesting story to tell and who knows a nice hold for the right collector

If you still have the encrypted file, then you may possibly recover your funds. I don't know how it would happen, but you need to research a bit about it and contact trusted recovery services. As we know, without seed or private keys, it's impossible to recover your funds. So if you lose everything, you lose the funds as well. I am not getting what you mean by artpiece. No access to your wallet means nothing can be done with that. 

Sorry to disappoint mate but I don’t think there is any creative way for you to turn this lost wallet into an art piece. Do you want to sell a screenshot or something? I mean you could draw it but it would seem like you just took inspiration and nothing else.

I don’t think there is any way you can benefit from this poor wallet anymore. Such a regret but you have to accept that and move on.
