Demo Apps

I have written several demo apps.
(1) A regular gadget with gadgets.* API
This is based on official youtube gadget presented here. Official youtube gadget uses traditional gadget API, which means it can not be run in open social containers.
I modified the source of official youtube gadget to make it compatible with open social API. Source is hosted here.
I run it on Ringside, and it works well. Screenshot is shown below:

Besides, I run it on iGoogle sandbox and Orkut sandbox successfully.

(2) An open social gadget
This gadget is written with Open Social API so that it can be run in all standard compatible containers. This gadget lists all friends you have in a container. If you add it to your Orkut account, it will list your friends in your Orkut account. If you add it to your hi5 account, it will list your friends in your hi5 account.
Source is hosted here.
I run it on Ringside, and screenshot is shown below:

Besides, I run it on iGoogle sandbox and Orkut sandbox successfully.

(3) A Facebook application.
This application gets your friend list on Facebook and displays related information including profile picture, last name, first name and birth date. You can see its information here. Meanwhile you can add it to your Facebook account.
Screenshot is shown below:
 

(4) A port of application (3)(The facebook application). 
Because Ringside implements Facebook API and FBML, application (3) should be able to be run on Ringside with minor modifications. New API key and secret should be used. Besides Ringside RESTful server (instead of Facebook server) address should be used.
Finally, I got it to run successfully on Ringside.

(5) Make Facebook to use Ringside application
I used the method described in this post and this post. It should work. But unfortunately it did not work. Currently I don't know why.

To try it in Ringside
First go to http://gf1.ucs.indiana.edu:8080/ to log in.
Then click tab "Applications":

Following page should be displayed:

Main panel displays a list of all applications you have added to your account. You can click any one to use it.
Or you can click button "Find More Apps" at top right corner to browse more available apps.
Application "youtube gadget" is the application (1) described above.

To run application (3), you need a Facebook account and add it to your account by accessing here.
