2. A developmental IDE that targets interactive run-time development where you see results instantly. Variables would instantly turn into scrollable bars that you can set min and max to modify a running game window. (i'm working on this idea.)
3. A service that teaches me how to program distributed, peer to peer, or machine learning step by step in implementing useable already made tools. Not just blog posts or coursera courses how to teach yourself how to make them.
4. An small box that you can program to respond to text with other small parts to turn lights on and off as well as other small things around the house for automation. But not be over the internet. A simple home automation by wifi sounds safer to me.
5. A plugin for the browser that track's movements and clicks of a mouse, for later automating a specific session. Useful for automation and faking users for social sites. This would probably have to be open source since privacy is a concern with plugins that provide that much level of tracking.
6. A finance screen that pulls off data in a more use-able way that isn't just simple stock figures but gives insight into market trends. This is a general idea, but the data needs to be useful enough. Thinknum, quantopian, and quandl.com are all decent ideas that are like "half-there."
