slowly working on online version

i finished the print version a while ago (available to buy on etsy), but i am now working on an online version.

unfortunately i couldn't find any existing tools that would let me easily publish it, complete with the folding/unfolding mechanic, so i've been writing a custom app in javascript. i started out using CSS transitions, but i ran into glitches thanks to slight timing differences between browsers. i ended up switching from CSS transitions to using tween.js, which is a nice and simple tweening library that works perfectly on different browsers.
