  If you're interested in developing this into a useful library, perhaps you should consider starting a Patreon (rather than a kickstarter). Having a monthly drip of money is probably a more sustainable model for an open source project than a lump sum payout with nebulous goals (that it looks like you've already achieved).

    thanks for your advise! Maybe I should give Patreon a try after the kickstarter :D this kickstarter is a quick-starter. https://creators.kickstarter.com/quickstarter/

    It is mainly for making new backer friends or have a good relationship with my potential customer of my web visual effect dev tools.

    thanks a lot for your help on overall direction of business model. have a super nice and happy day~!

  I'm sorry for being slow on the uptake, but … what is it? I mean, I see four text panes and a glowing light, but why?

    Hi @JadeNB, here's the kickstarter preview video that explains this tool :) https://youtu.be/WwDu8aMIYZA thanks for your query~ :D

    That's literally it. It's graphical particle effects. Think of simulating sunlight on water, or laser blasts, that kind of thing. Just happens to run in codepen, is all.

      Yes :D It's fun to play with the way things could be through imagination and code. :)

  Wow! That's an intense particle. I'm thumbing through the code now. Nice work so far!

    aww thanks a lot for your kudos!! :D You can try try replace similar code with these code...

    vec3 ball1 = ballify(vec3(x, y, z), 1.0);

      nextPos = ballify(ball1 + nextPos, 17.0);
      
      nextPos.x += cos(nextPos.z - time * 30.0);
      nextPos.y += sin(nextPos.z - time * 30.0);
      
      nextPos += getDiff(nextPos, mouse * 17.0) * 50.0;
        
      gl_FragColor = vec4(nextPos, 1.0);
