please give me some thoughts on a new idea for software engineering final year project! Complex, the better

A WYSIWYG editor to generate applications with the possibility to choose the language of the code generated?

Building an exchange (that matches buy/sell offers) of more products/or currencies, and their prices are automatically updated based on the demand. You can also make money after it with the cryptocurrencies :))

Build an server/client like Meetup.com, there aren't many around.

I just answered with some ideas on a different topic

Later: that post was removed or something, all my ideas are gone :( let me see if I remember)

• I want to know if I forgot any water Tap on when I leave the house (motion or noise detector near the taps)
• generate entropy from the nature, see how others do it
• if GPS counts imagination is the limit (bikes, kids, find patterns, alerts)
• make a framework that links IoT (alerts, triggers) to push mobile notifications (example pusher.com)

That's pretty broad, any clues about what you might be interested in? Can the domain/technology be literally anything?
