Re: animated backgrounds
You want real desktop animation crack? Here is what I want. I want to do a desktop version of the Museum of the North's "The Place Where You Go to Listen" http://www.uaf.edu/museum/exhibit/index.html "The Place Where You Go to Listen is a unique sound and light environment created by composer John Luther Adams. This ever-changing musical ecosystem gives voice to the rhythms of daylight and darkness, the phases of the moon, the seismic vibrations of the earth and the dance of the aurora borealis, in real time." All the data that art installation uses is available publicly through the Geophysical Institute's real time monitering system via the web. I want to see something similar for the desktop except do this without sound... do it only with animated svg desktop elements! -jef"I wonder if there is NSF funding for this.

Re: animated backgrounds
Hey, I like this idea a lot but have a question about the current usage as well. Currently you seem to use png images and 24 for one day. isn't it better to make 1 SVG file and change the gradient settings in the svg through a (xml? or script?) file? than you only have one image and is flexible for people that want to adjust it. perhaps also better for the CPU cycles? Seasonal changes would be funny as well 1 Summer - add beaches? 2 Fall - add falling leafes 3 Winter - add snow 4 Spring - add starting flowers But that's gonna be a whole desktop animation program ^_^ ___ Fedora-art-list mailing list Fedora-art-list@redhat.com http://www.redhat.com/mailman/listinfo/fedora-art-list

That's four pictures, but if you left it to that then the background would change too much in every 6 hours, you can then either make longer transition phases in the background definition, but it eats a lot of cpu cycles, or made the transitions manually in gimp, for one hour one picture, which is more work and more disk space, but the result is IMHO the best. As I noted in my previous e-mail I tried to do something like that, based on Mo's wallpapers. The result is now finished [1]. I however not leave it there forever as it needs a lot of space, so when we replace it with something better, or include in fedora, I'll remove it. Your idea with the mascots and birthdays is great! Now we only need two things: the mascot and the ability to choose special sequence on the background based on user personal data...

I am now making some changes to the wallpapers Mo created. I picked what I thought best for 00am, 04am, 06am, 09am, 00pm, 03pm, 06pm and 09pm (i.e. 00am midnight, 06am dawn, 00pm noon, 06pm dusk and the rest is somewhere in between) and am doing now the hours between by transitioning them in gimp - I think it is good to have one wallpaper per hour, but as a start what you suggested seems enough, but making the transitions in gimp is less CPU intensive than letting the gnome do it for you. Regarding the seasons, I though it would be great if there was a feature to add subsets to the transitions - i.e. we would have one 'wallpaper' staying for e.g. 3 months, but it would not be one picture, but another slideshow with one picture per hour. In code it could look like this: 3 3595 /usr/share/backgrounds/fedora-infinity/spring-am00.png 5 /usr/share/backgrounds/fedora-infinity/spring-am00.png /usr/share/backgrounds/fedora-infinity/spring-am01.png 3595 /usr/share/backgrounds/fedora-infinity/spring-am01.png 5 /usr/share/backgrounds/fedora-infinity/spring-am01.png /usr/share/backgrounds/fedora-infinity/spring-am02.png ... 3 ... While it does make sense in providing thus greater configurability and ability to change the wallpapers not only by hours but also by season it would be probably harder to implement.

With the original version, where Luya had the transitions set to 5.0 and still images to 1.0 it ate a lot of CPU cycles (during the transition it was even on 100 %), so when changing it to rotate accordingly to hours I set 2595 for still images and 5 for transitions. It should sum 24 hours, but it seems precisely one day (i.e. 24 hours) after the set start time it changed with 10 minutes or so delay. I am now waiting for next whole hour to see, how's it now (approximately 34 hours after start time). And btw. the change that enables timezones actually works (I tried it soon after the rpm was built, what a coincidence) :) Martin signature.asc Description: This is a digitally signed message part ___ Fedora-art-list mailing list Fedora-art-list@redhat.com http://www.redhat.com/mailman/listinfo/fedora-art-list

Is it possible to create some kind of settings to show these in KDE?
