Here my concept of how instagram would look with material design. Material design is the next step in Google's design evolution for Android. Also, some animations transitions may be too much but it just there to showcase what can be and to showcase separation of elements.
*This is a 60fps video but I guess Youtube has not rolled out 60fps for everbody yet (I think).
Special Thanks to WWJOSHDEW and BANETECH on youtube for letting me use their photos from instagram. Check their channels out.
