Here's a quick mock prototype of a Fan app.

After doing the initial UI coding, which took me about 2 hours, I started adding the real functionality (simple scrolling, toggles, buttons).

Here is v0.1 mockup screen:

Jan.17 UPDATE

• added spinning fan blades feature
• added fan on/off on tap

Jan.20 UPDATE

• The fan sound has been added (it's horrible though, need to find a better one)
• The sample music has been added (1min long) to the first soundscape tile
