My spouse is a special ed teacher. She was pretty excited to see this- her last school district had an entire office devoted to cheap, practical affordances like this. I can't wait to see at-home manufacturing / 3D printing start making on impact in this space.

Ironically, the design of this site actually inflicts physical pain on my eyes.

Very celver and I applaud sharing this kind of innovative thinking. And for free. Also I'd like to give some credit in that the site doesn't try and dress up the material as "life hacks" or some other kind of puffery. It's not the easiest to look at unfortunately. I do like simple and this is close to basic, just probably not a personal fan of the color scheme. That's kind of a nitpick which thankfully I do believe is overcome by the usefulness potential of the content and time spent on the site. The About page is a nicely done example I can appreciate too.

I love the actual content of the site. But the design is trying to be way too clever, and fails for usability. I would prefer a UI that is simple, readable, and easy to navigate.

Goes to show how engineering is born out of necessity.
