Today I posted a short video preview of a small feature I added to Keyframes - it uses your device's orientation sensors to adjust the CSS box shadow. A cool little effect. As of right now it's at over 3,000 upvotes and is #1 on /r/web_design, which is pretty cool.
And now I'm also launching on Product Hunt! If you'd like to discuss Keyframes or leave me some ides, join here: https://www.producthunt.com/posts/keyframes-app-2
