Besides mandibly death? It reminds me of a pseudosphere, or maybe a hyperboloid, lookit that negative curvature, right? It's roundy one way around the funnel but unlike a sphere which would be roundy around the same way it's roundy around the opposite way at the same time. it reminds me of this sculpture by Anish Kapoor called Vortex which I guess doesn't photograph very well but trust me in real life it just sucks your mind into this incalculable void and you're left standing there staring helplessly with your brain all fuzzy. It makes me imagine the entire room could get sucked into the roundy vortex of spiderness, or at least the bugs in it, like flies are points in a vector field and the vector field is like choochoochoochoo into the funnel, or maybe it's a spirally kind of vector field where everything spirals in... I looked it up it's a funnel web spider, not to be confused with the australian funnel web spider, and its funnel is more a cozy retreat for the spider to hang out in than a place where bugs get stuck, it's not even sticky, the bugs can fall on any part of it or even just be near the web and the spider comes out and does noms. So its kinda like the web extends smoothly to become the couch and the rest of the universe... It makes me think we are all already inside the web we just don't know it yet because the spider hasn't come to claim us, it reminds me of a 4d torus stereographically projected into 3d space, there's this cool way to divide space into like two infinite donuts, whatdya call it, ooh that's what I'm talking about, thank you Jason, so you think you've got a regular donut but it starts growing cuz spiders and soon it's infinitely big inside and everything is spider territory and there's this funnel web spider hole but actually surprise, the rest of space that isn't the donut is actually also a donut that belongs to reverse-spiders or antispiders or something. I know that's probably not what the spider had in mind when it made this web in the corner of my couch buuuuut I can't help wonder when presented with such a shapey shape. *it's making me have math thoughts* Ok postscript, no joke, I went to see if that Anish Kapoor sculpture was still on display at sfmoma and the 5th floor sculpture gallery is now entirely full of spiders. By Louise Bourgeois because she knows what's up. So here's some free promotion for sfmoma, go do art to your brain its good for you bye.
