As 2012 drew to a close, we asked you creative types to let us in on your forthcoming crowdfunded projects -- and boy did you deliver. We've spent the past week whittling down the submissions for our first-ever Insert Coin: New Challengers competition, and are pretty excited about the results. As detailed in our announcement post, we've chosen 10 semifinalists, who will receive a free trip to Expand next month, along with a $1,000 travel stipend. Better yet, those on the list are in the running to win a total of $25,000, including a $5,000 Reader's Choice award and $20,000 Grand Prize, along with product reviews on this very site.

Congratulations to all the winners and a big thanks to everyone who entered -- paring down the list wasn't an easy task. We'll be highlighting each entry further in the week to come, leading up to a Wednesday, February 20th, vote for five finalists. Skip on through after the break to check out the list of semifinalists, and we'll see you in March!
