For those looking to make an entrepreneurial splash, Entrepreneur Magazine has found 10 industries to look toward in this economy. A lot of the bullet points on the list make sense for the times–secondhand goods and discount stores are obviously seeing new customers as more people looks for ways to cut back.

The aging baby-boomer generation also accounts for a spike in medical office building needs, and social networking is no shock, with Facebook and Twitter showing up on nearly every list these days.

The unexpected industry on the list was 3-D, as in the flimsy glasses that make half the world red, half the world blue, and everything a little more dimensional. The magazine reports that improved technology is expanding the number of contexts in which these glasses can be used effectively. Perhaps the increased demand will also lead producers to find a way of enabling viewers to see the world in 3-D without looking silly.
