CodePen probably won't work great in this browser. We generally only support the major desktop browsers like Chrome, Firefox, Safari, and Edge. Use this one at your own risk! If you're looking to test things, try looking at Pens/Projects in Debug View.
Many of my CSS illustrations in a lo-res edition to showcase at CodePen Hamburg Meetup on Oct. 10, 2017. FYI at our Meetup:
Lo-res canvas: 128×256 in the upper left corner, or responsive
Dark background preferably
At least 1 pen named "Lo-Res" or a collection like this also named "Lo-Res"
It doesn't need to be your pen(s), but also could be fork(s) of your favorite pen(s)
