In the latest Android Design in Action episode "Android Design in Action: Design Hangout No. 1" Roman Nurik encouraged the Android community to show their skills in giving the old apps a new refreshed look. To see what people have come up with search for the competition tags on Google+.
The quality as well as the quantity of redesigns submitted to Google+ this week is surprising to me. Just few short months ago it was impossible to find designers who understood Android but that is rapidly changing. It could be that more an more designers understand how good of a career step learning Android design is now that Android has captured more than 75% of the global smartphone marketshare.

Marie Schweiz's BloggerWhile Marie's Blogger design isn't actually from this week you can't really talk about app redesigns in Google+ without mentioning her. Her take on Blogger is something I'd hope to see become reality soon. See Marie's post as well and her other redesigns in her Google+ stream.
