Super loud sound warning, us parents and folks wearing headphones would really appreciate default sound off. Or at least a some indication to turn volume down before tapping "pour"
Comment on Hacker News · 2 direct repliesI notice that different types of sand sound different - the timbre of the sand falling onto the table and shuffling around is noticeably different between the various types. I was curious if the differences in the sand were being physically modeled to synthesize sound. It’s a physics-based generation but the simulation model is somewhat limited; essentially a few parameters that vary between the sand types, some randomization, and responsiveness to flow rate. Still, it’s highly effective; something like the fine, silty desert sand is noticeably brighter and sounds more like a hiss as it pours and flows than the rocky volcanic sand. Very cool effect, this is joyful to play with.

Comment on Hacker News · 6 direct repliesSomething seems wrong with the stones. They seem to move way to fast. They need more friction.
Comment on Hacker NewsI just spent 15 mins playing with this on my phone, it was a lot of fun!
Comment on Hacker NewsSmooth on OnePlus 13. Some flickering on the side the sand falls hard to. Still very nice.
Comment on Hacker NewsTried this on desktop and mobile, totally different experiences. I love the residue effect on the screen after I tilt the sand around on mobile. Next step: hourglass or maybe a snow globe?
Comment on Hacker Newsoh wow, the stones even have some water around them. This looks and feels real. And if you manage to collect a lot in one place, the sand from the pile does fall like real sand. This is amazing. The sound is not good though.
