Been kind of sick the last week (and recovering now) so I haven't updated much. Lots went on but first let me show you what I found a poster at Gizmodo came up with.
He created a UI based on Star Trek TNG's touch-controls for the iPhone. It doesn't turn your iPhone into tricorder or disrupter but it's awesome how it worked with the iPhone's OS and functions.
This is definitely an area of development I like to see put some effort into developing. I'm sure there are other cool sci-fi themes folks can come up with for the iPhone or other devices.
