As you've probably noticed, a bunch of the Gallery's Gadgets have two buttons on them “Add to Live.com” or “Add to Spaces.” We added this functionality a few weeks ago in sync with the latest release of Windows Live Spaces to enable you to easily choose web gadgets from Gallery to customize your space. Since then, there are a few cool web gadget examples we’ve noticed on the Gallery site from our community – here are a few:

1. iTunes Songs – created by LiveGadgets – has already had over 30,000 downloads!
2. Hangman – created by ToddOS1
3. Simple Calendar for Spaces – created by JeffreyZhao_Fool
4. Cool Pictures from Windows Live Spaces – created by DarefromMicrosoft

The Spacecraft, the Spaces team blog, has a great overview on creating cool web gadgets to run on both Spaces & Live.com, here’s a snippet:

“Remember that the Live.com portal is about YOU catching up on the world.   Spaces is about the world (however big or small you define it with the permissions you set) catching up on YOU.  Users will decide which gadgets are worthy of adding to their space or not, and given our experience with Spaces features to date, the ones that will be the most successful will be:

Customizable -- let the space author personalize the gadget so their instance of it is different than another Spaces user's instance.  This could be as simple as letting the space author select the city they want to show weather for OR as complicated as pulling the user's account data in from another service (ie, his/her Netflix queue). 

Reflective of the author's personality -- a gadget that helps the author to be creative with little or no work is more relevant than one that lets a visitor come to a space and check their mail account or convert their currency.  All of those gadgets are killer apps; it's just the ones that are more like sharing your photos or music tastes will probably be more popular. 

Adaptive to our rich themes/layouts -- after adding your gadget to your own space for testing, try selecting a bunch of dark and light themes AND moving the gadget between our narrowest and widest columns to make sure it works well in all scenarios.  You want that puppy to shine!”

Wanna create your own? Here’s how to get started: 

1. Build a Windows Live web gadget according to the SDK available at the Windows Live Dev site. Don't forget to take a look at the Spacecraft post for the 411 on optimizing your gadget for Spaces (author mode for personalized settings).
2. Zip up your manifest file and supporting Javascript/CSS files and submit that gadget package to the Windows Live Gallery so other Spaces visitors can add it to their space by going to Customize --> Modules --> "Add gadgets from Windows Live Gallery".  Once it has been verified to work in each service (we will do this step as part of the check in process), it will appear in the Gallery for users to add to Live.com or Spaces.  Make sure you use relative URLs (mygadget.css instead of http://foogadgetdeveloper.com/mygadget.css) in your manifest XML to point to the scripts/CSS or the gadget will be rejected during verification.    
3. If you tricked out your space with Gadgets or come across a cool space with Gadgets drop us a line by commenting on this post, or you can send mail to spgadget@microsoft.com. Same thing applies if you have feedback or feature requests for making gadget development for Spaces better.

We'll be updating the Gadgets SDK and sample code on http://dev.live.com soon to reflect the additional Spaces info.
