I managed to wrestle this code onto my site, you can generate a visualized image of your npub with it. It’s also live so you can just type what ever in there and see it convert in real time the characters into lines with hight based on the ascii as hight. Couldn’t get a download button to work, but you can right click the image on desktop and save as a png. On mobile just screen shot it.

Check it out, it works for my private key too
😳 eh, so, I did think about this, wasn’t daring enough myself to post… I have no clue if this can be reversed engineered, daring if it is your nsec… doesn’t look like your npub cause your is #c# and there isn’t a second orange line
Its just the default key from the site, just a bit if a joke before I head to bed, cool site though
have a good night, I might make an npub tomorrow and post the nsec as a visualization and offer a small reward to post from it
ok thank god it’s not an nsec, the first purple lines would look like this
