Android apps

Hey guys, this is my first post.

I'm android fan just because I like customization.

I'm from India. I ordered Samsung Galaxy Nexus yesterday for Rs. 22,500 ($400 approx) which I'll be getting within 8-10 hours from now...

Any suggestions for the apps?
Actually I need some apps like quick camera shots like in HTC One X.

And btw, is there any app in Play Store which can animate the photo just like in the New Nokia Lumia 920.. I'm not talking about image stabilization as it requires floating lens(hardware).

Any advices and recommendations? This is my first android phone...

Thanks in advance guys..
