In my experience, if somebody claims something works, but I haven't seen it, the safest assumption is "doesn't work". I happen to be in my phone now, and I'm not going to bookmark a site in the "doesn't work" category. Maybe if I happen to check HN from a desktop later and the link is still on the front page, I'll give it another look. Otherwise, goodbye.
The site lets you choose a lot of parameters for CSS3 animations and shows the effect on a number of selectable objects. It then lets you download the CSS3 code with your selected parameters, so you can use them in your own CSS.
CSS animations work, any individual browser bugs notwithstanding. The nice thing about this site is that you don't have to guess all the CSS `@keyframes` and `animation` parameters to match some vision in your head, but you can visually experiment.
The actual value of this site is the interface, and I can see why it would be hard to make it work specifically for mobile devices.
"Trust me." Yup... not something I want to invest my time in if I can't see it work. A message telling me not to use the mobile version reminds me way too much of those, "Please use IE6!" messages we got back in 2004 when a site wasn't tested on Firefox or Safari.
