Could something like this be done with the API? (Tokens and Light)

See this xkcd comic: <a href="https://xkcd.com/1663/" rel="nofollow">https://xkcd.com/1663/</a> Click the grow light and use the triangle control to change the direction and angle of the light beam. Use the dot control to change the color of the light. Anyone know how this was accomplished? Was it just HTML and JavaScript? Could the API duplicate something like this for tokens?

Yes, this could be done with the API by leveraging some clever math, but it won't allow you to adjust the direction and angle of the light while its triangle is being dragged. It would have to take effect when the triangle finishes getting moved.

Thanks for the replies and the info, Stephen and Brian.
