Am sharing an apps called "Tegaki Messenger" which I just downloaded today. Basically it's something like a "message" where you can draw or type in it then send it to your friends. I kinda like the idea and somehow it reminds me of "Draw Something" apps in Android (Of course it has nothing to do with guessing games...But ah...it's fun to draw during leisure time ok!).
As usual, if you're interested, CLICK HERE to register or download. It's pretty simple so I don't think you'll have any problem with it.
An example of what you can do with it
Be sure to buzz me if you're in it. My number is 515-6210-2032. See you in Tegaki Messenger! * disappears into the thin air*
