What had you expected? You men can wear the same suit for years ... So stop sulking!

[:)] Me, sulk? Never! And women waring the same dress twice? Perish the thought.

..entire light source above the ceiling, you definitely need a cut-out for the light to be visible...

Oops, seems I did not test as thoroughly as I thought. You are absolutely right. Good news is that the SVG exercise can be of some use.

How did you make the SVG-file with the animation?

Short answer is: with the help of a text editor.

Longer answer is that the trouble with SVG (and to some extent with HTML / CSS), is that most editors are limited and do not really let the user exploit the full potential of the format. Inkscape, for instance, is a wonderful piece of software, but does not (I think) support animations natively. Which means that I amateurishly try to do like my more competent (and puritan) friends, write the code manually.

The animation in thread 7108 was just a first experiment. Basically just using W3C SVG Animation and MDN <animate> code plunked into and SVG file with a text editor. Not elegant, but I proved to myself that it could be done without too much effort.

SVG animation has a great potential, including the possibility to animate raster graphics supported by SVG (like png/jpg). A downside is that it is not supported by Microsoft / Internet Explorer.

ok

PS BTW, there are several techniques to animate SVG, including CSS.
