need some ideas websuite/app

okey, since this is the only place with people with half a brain, i need an idea of a website i need to make for a university assessment. yep, im coming here out of all places..

Some ideas they gave us was:

1. An Fun and Stimulating Educational Interface to teach English for Young Children whose first language is not English
2. A 3D visualisation tool to simulate buying furniture at IKEA
3. A single student app that integrates all student apps in one
4. A mobile app that translates teenage slang in received messages and emails for the elderly
5. An Interface that tracks energy usage at the home and provides alerts, suggestions
6. An Interface that tracks the medicine intake of patients at home

So I need something I can work with pretty much.

Im going to be using c# and visual studio for most of this..
