Here is a very basic prototype of an app I am looking to have developed.

Pitch

umu assists parents in challenging situations. A crowded day at the beach, a theme park, you name it. A tiny transmitter is carried by the child which's signal is received by the smartphone. When the child is bound to move out of sight or towards a dangerous sight such as water or a busy intersection the parents are alerted. see more at: http://crafting-convenience.com/umu/ Feel free to contact me at: jason@hello-bright.nl

This simple prototype demonstrates how have a container expand and collapse while moving adjacent content in sync.

This is a prototype for a café discovery service that I'm developing and it is purely for idea conceptualization purposes only! Please leave comments and let me know what you think!
