Sorry to be a bit of a killjoy, but I find the snowflake animation on the page annoying. Nothing serious, of course— I read the article in its entirety ;) But ironically, in the case of this article about icon design, the icon for the warm/cool color theme toggle button in the site header is a snowflake (and it doesn’t change when switching to warm colors). I initially thought this button was meant to disable the snowflake animation :D
