Just tested with canvg.js Canvas2D render. Looks terrifically crisp and clean even scaled way up. Thanks for building!
The icons are awesome.
I also wanted to comment on the website. It's simple and I love it.
Nice, thanks. How about a CSS scale property on hover to magnify the icon.
Can you add license information? It seems all three sources use MIT "The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software." and it's not clear how many of the icons on the page are from whom, thus being a substantial portion.
