iPOKE!

iPoke application caught my attention immediately, when apps were introduced in orkut.
You have to add the application to your profile first.
Now you can poke your friends..
You smash birthday cakes, throw flowers, bowl googly or smash tomatoes etc
If your friend has this app in his profile, in the top 3 order, then his profile will show the pokes he received from you and others.
You can also view the pokes that you sent through your history, from My History tab in iPoke tab.
