There are such a plenty of Twitter apps recently that at some point I stopped paying attention to them. Still this app made me spend a few minutes figuring it out (and trust me I am a busy girl right now).

SayTweet allows to create a huge Twitter badge using any image you upload:

• find a cute image (best if it has a face and mouth to speak);
• give your / anyone else’s twitter account name;
• you are done; now this twitter account’s updates will appear in the image:

The tool also allows each badge embed.

The site is searchable by Twitter name and keyword / badge tag.

The site seems a bit slow at times but still worth the time
