It seems like with some recent Android update or other, they've locked down the ability for Chrome to read local files; they can't access any other referenced file, use cookies, etc. The index.html file would load, but just as a white screen with text in times new roman and no cookie settings could be saved or retrieved.
I used an app called Simple HTTP Server, pointed it at the folder where I stored all the files, then it hosts those files on a 127.0.0.1 IP address that Chrome will load and treat like any other webpage. Then I just set a shortcut on the device's home screen to that URL. If it's OK with you, I can share my files so others can take advantage of them.
I also made a fork with a couple other features I was fiddling with - even though they don't ever light up in the show, I wanted the LEDs to do a little more than just sit there, so I added some random blinking boxes behind them, as well as a toggle to disable them if screen-accuracy is the priority. The top light blinks quickly between red, green, and white to give some varying illumination levels and the bottom light blinks slowly between off and on.
I also added a volume control so the animations can run without sound without needing to take the device out of the shell to adjust the volume; while the animation is playing, tapping the first symbol adjusts the volume, and tapping it while the animation is paused resets it as usual.
