I am super impressed by this. The landing page is GREAT, it really shows you what it can do and I tried creating a polypad and it works just as well as the landing page makes it seem.

I would have loved to have this when I was in school and I can imagine it is a great tool for teachers. I am going to let my kids play around with this.

In rereading my comment it sounds like some sort of lame ad, which I can assure you it isn't. I am just excited about it.

Same! It’s one of those projects where as soon as I scroll the landing page, I can hear the fireworks of ideas going off in my head! It seems to work really well on mobile as well. I think it’s got real visual aesthetic appeal - it takes me right back to the handdrawn colour diagrams in the textbooks when I was at primary school.
