Emoticons are a simple way to disambiguate text messages and to add a human touch using a minimum amount of characters. While Gmail Chat supports many emoticons, the full lists of emoticons that can be used is much bigger. TKHere tried various combinations and found some undocumented emoticons in Gmail Chat:

In the screenshot above, you can see a diabolic creature (}:-)), a crab (V.v.V), a wince(>.<), a broken heart (</3), a kiss (:-x) and a mustache (:{).
These emoticons only work in the new version of Gmail and can be disabled in the chat section from the settings (note the cool permalink).
Meanwhile, the Japanese Gmail started to support emojis, pictograms popularized by i-mode mobile phones. "These images can be used as placeholders or icons to identify a link or other elements in your page. There are emoji of common use such as airplane or a train and there are some that may indicate emotions, sun, moon phases and more," explains The Wireless FAQ.

Sinographs of Kanji (Chinese character) originally evolved from graphics thousands years ago, and had become abstraction of graphics to represent objects and actions etc.
Now Japanese go back to the root, and use graphics again, in the ego system of computing devices like mobile and web.
Anyway, we are going to have to learn another fashionable language as it is going popular. What a fun.

Chintu,
Do you have any information from your Google contacts if they still have a team working on the Google Talk Desktop Client? Are they ever going to update the client? Should I consider moving to Yahoo messenger again?
@Anonymous:
Apparently, the answer to your question is yes and we'll see a completely new version. I don't when it will be launched, though.
