Hey Guys, I remember there was this really cool minecraft particle generator

So this is not exactly a question but its also a question so idk where to really ask it but 😭 I am making a datapack ||quite obviously || but to spice it up I was thinking of adding particles and I recall in the past, I used this website (which I found from this server) which generated particles in like proper shapes like spiral etc etc etc, a generator- based on graphing and stuff- NOW I FORGOT THE NAME 💀 And been tryna search for it for like past 1 hour 😭 😭 if someone knows ab it can someone please tell 
I remember it created like the whole mcfunction which had like an array of like tens or hundreds of particle commands on average and stuff to make it into a shape AH- I DONT REMEMBERRRR 😭
