Animated GIFs of the Machinarium robot dancing, and the officer with a teddy bear?
Solution 1:
If all you want is icons at the end of the day then follow the following steps:
download any screenshot utility. One example is here.
Create your own animated gifs to your hearts content using another utility. Again there are hundreds of options. One quick example is here. This is an ad supported version but at least you'll get access to the full functionality.
Now finally, you can create your own icon set totally customized to your liking using another tool. Again there are hundreds of free icon creaters out there. Here are a few examples: http://icofx.ro and http://www.free-icon-editor.com
Don't worry this whole process should not take more than an hour or two at most. At the end of the day you get exactly what you want and its more rewarding. Let me know if you have any problems.
Solution 2:
As for the robot dancing with the band, there is an animated gif of that here. You could get their "small" version, or just crop the part of the image you want using a tool to crop animated gifs like online-image-editor.com. There are probably more of them out there. Just scour through imageblogs like tumblr or twitter. I found this cutsey version of him dancing at tumblr for example.
You could always make animated gifs yourself with screenrecording software that outputs to images, but this will take some work. There has been a question related to that on superuser.com, this will probably have some caveats and bring its own set of problems.
