This app does not run any ads, at all. It even does not connect to internet. Hence I really cannot get what do you want to say by that.

What's new

Fixed glitch in ray rendering for the converging lens with object distance < F. Thanks for the physics teacher reporting the bug.

Prism reshaping rewritten to keep the same light source orientation.
