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).
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.
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~!
