Welcome to Cool Stuff, a weekly feature where we post our favorite links from the past week, including our favorite articles and how-tos, videos, images and more. Things have been quiet over the holidays, but there’s still a bunch of neat things around the web.

• We’re gonna start things off by quoting Popular Photography magazine here: “If you think your eyeballs are on fire after a marathon session editing in Photoshop, consider sorting through 1,200 rolls of film with slides, a loop, and a light box.” Check out the video below – and yes, that IS Joe McNally in a mustache.
• Speaking about a blast from the past, here’s how spy satellite photography worked in the days before digital imaging. Hint: They used film. Really.
• Now here’s an interesting twist on things. The folks over in New Hampshire have proposed a law that would lead to criminal charges against TSA screeners if they tried to prevent you from recording them at airport checkpoints. Yes, you heard that right. It’s a law aimed at increasing traveller freedoms, not decreasing them. Go New Hampshire!
• They may be down, but they’re not out – yet. Olympus is besotted with legal and financial issues, but that doesn’t mean it’s not working on new stuff. According to TechRadar, they’re working on a revolutionary new camera with an “epoch-making” viewfinder.
• Of course, Olympus will have competition from Fuji, which is still working on its interchangeable lens camera. Petapixel has the latest leaked image on their website.
• From the “he did that how…?” department, photography Anthony Chang made an awesome image of a liquid rose.
• Remember that awesome time-lapse of the planet from the International Space Station we showed you a while back? Here’s how it was made.
• Look, we pack heavy when we go on photographic trips – we admit it. But what would we carry if we had to go into a war zone? Well, here’s what one Reuters photographer decided to lug along.
• If you followed our FaceBook page, you saw this mentioned, but here it is again: The winners of National Geographic’s 2011 photo contest.
• We leave you with a warm, feel-good story. An AP photographer tracked down a wounded Marine to give him a memento of the battle that led to their meeting.
