Hi all, Two new images for your perusal, both by Stefan Weber. I think Stefan is also new to Wikimedia, so welcome, Stefan. R1-28 - Cone clutch https://jira.toolserver.org/browse/PGIP-54 http://commons.wikimedia.org/wiki/Image:Cone_clutch.svg R1-30 - Császár polyhedron https://jira.toolserver.org/browse/PGIP-56 http://commons.wikimedia.org/wiki/Image:Csaszar_polyhedron.ogg This is our second OGG animation, very different to the first one <https://jira.toolserver.org/browse/PGIP-26>. I am really impressed by the animators' creativity and skill. To be honest, for animations I thought people would do animated GIFs, those awful things. :) For OGG animations it is a bit more difficult to judge the "correct rendering" aspect, because MediaWiki's in-browser OGG player is not as robust as its SVG rendering, from my observation. (I can't even get the videos to play at all because of some Java thing...) Anyway for the OGG animations I think the best way to evaluate them is after downloading them and playing them on your own machine. If you have trouble playing this format, I strongly recommend VLC media player, available for Windows, Mac OS X and Linux. <http://www.videolan.org/vlc/> cheers, Brianna -- They've just been waiting in a mountain for the right moment: http://modernthings.org/
