A couple of years ago I produced this as a study into procedural heightmaps, shadow mapping and online geometry loading with Three.js. I had big plans for it but abandoned it half way.

I found it on my hard-drive the other day and thought it might be worth putting up in the case that it's of any use to anyone! The project is full of performance issues and other weird things but hey I hope it's worth something! Enjoy.

Code lives here: https://github.com/alexanderperrin/threejs-ballooning

Works on desktop and (most) mobiles. You can use the arrow keys or touch the screen to move the balloon.

Super glad it's working for you! May I ask what sort of device you're using? I'm quite curious.

Works flawlessly for me on a Pixel 2XL, quite surprised.

To give you second data point, it crashes (probably OOM) on my $39 phone.
