Repeatedly click the dots for a tutorial, click and drag to rotate, and – after writing a function of your own – hit "enter" to generate a shareable URL!
Let me be clear: This thing is wholly derivative, merely adding a third dimension to Martin Kleppe's excellent creative code golfing tool tixy [0] (which you should definitely check out if you find yourself liking this 3D variant of it) by mashing it up with David DeSandro's equally-excellent 3D library Zdog [1]. Those two deserve any and all credit.
I don't think "deceptively" is the best word here – there's no money or private data involved, at most a small bit of street cred. The near-identical look was intended to preserve the simplicity of the original. Note that there's a reference to tixy.land in my comment here, in the README.md on GitHub, and in the tweet that's behind the "more info here" link. Anyone looking to do more than just idly play around with this tool will come across one of them.
But I get your point – I'll be adding an unobtrusive link back directly to tixy.land soon!
I opened your page, saw the thing and the first question was if it's from the same guy or not. There's no answer and there should be. tixy.land is an ingenious, one of a kind construct. You piggy-back on it, it's only fair, polite and respectful to give a credit. Basic manners, really. A simple line at the bottom of the page saying "inspired by tixy.land" would do the trick. The fact that you instead chose to argue that it's not needed is really quite bizarre.
I doubt it was your intent, but at the very least you should give the credit to tixy.land, with a link, front and center right there on the page.
Also, something as simple as using a different color pair would really help to distance it from the original.
