like i allready announced, the next website is up and running:
www.kuss-kultur.de
i am sorry, but until now there is only a german version, but hopefully there will be an english soon.
it is the website of my mum
and i think it was one of the fastest websites i've ever made...
now to the technical specs:
frontend: completly AS3/Flash 9
backend: umbraco v3 with imageGen PlugIn and the really really cool umbracoTags Plugin by Per Ploug Hansen
when i have got some sleep i will write even more about it...
but again i love the simplicity of umbraco! 
hej,
another website for a customer is online. the frontend is realized with flash 9 and the backend with umbraco 3.
i am really pleased with umbraco again. it was so easy and quick to implement everything and write a xml-output for flash.
you can see the website at www.kostron-mode.de (german only, sorry).
in the next few days there will be the next site online. also with umbraco v3 and flash 9. and in this site i will use the umbraco tag package by Per Ploug Hansen.
so look forward 
www.dalhalla.se
now my internship is over, i have had a lot of fun and i really like, the work, the guys (and girls) and of course the tools 
after seeing umbraco.base, i was kind of motivated to build something on it.
i tried a little bit around and liked stuff like the auth things... and the rest.xml file to handle different thing.
but i would like to use flash, and so i have googled around and found this. And so i thougt, umbraco needs an AMF interface... umbraco.base is really nice, but amf is more comfortable for flash.
and this is my new project...
so i am currently learning C# (what is not that hard ;]) and trying to start a powerfull umbraco extension for flash...
but hope to get some good tips from Per Ploug Hansen maybe on the user and auth stuff
BTW: i am not implementing AMF in C#, i use AMF.NET and will connect it to umbraco!
here is the second official launch from me at tewonder:
http://astridlindgren.sos-barnbyar.se/
it is, again, made with umbraco.
dynamical flash detection, with fallback image solution, everything of this can be done in the cms
it's the second launch, but there are 3 other websites, made by me and umbraco ready, waiting to be launched.
so look out... ;]
