They're also looking for donations. If you're in a Burner community, you're aware that there'll be a lot of opportunities to fund art and mutant vehicles and sound camps and so on, and of course those are all excellent (though some are more excellent than others).
What Que Viva is asking you for help doing is funding artists themselves, particularly underrepresented ones. It's way too easy to spend all your attention on the 'big' art at Burning Man, and miss great projects like this one that, to my mind embody the spirit of Burning Man.
I think it's pretty cool, and I'm donating. I hope you'll consider it too.
This page explains what the funding is for. Mainly for tickets and tents for the low/no-income artists, and art supplies. Donation link is towards the bottom of the page.
