Comment on Show HN: Gravity – Interactive solar-system simulator, from Newton to Einstein

Comments

This was a lot of fun to explore. I find that naturally I want to click through the animations and observe them for a while before delving into the steps and reading the blurb. It's a bit like skimming around a textbook's headings & figures before reading the chapter, it builds motivation and interest.

One simply change to improve the experience is to keep the Next/Back at fixed locations. The animations and transitions are beautiful, and looking away to chase the moving buttons causes me to drop the visual context.

As a workaround I set the height of .tour-body to 900px and the the whole thing became so much more immersive, like the old planetariums.
