I ended up taking two chairs from the dorm, a picture frame, and a clamp lamp. Set the picture frame (with just the glass) as a bridge between the two chairs, clamp the light to the chair below the frame, and voila! Collect snowflakes on the glass and have at it 
Here's a shot of my super-legit (lol) macro setup I used this evening:
Looks a bit silly, yes, but it's far more serious than anything I've attempted in terms of snowflake macros before. Usually I just shoot whatever flakes fall on the deck railing. However, that doesn't always work out lighting or flake-wise (you need fairly large flakes to make that work). The advantage of this backlit setup is that 1.) when you look down at the snowflakes on the glass, they become a perfect silhouette, and 2.) by looking towards that light, you get much faster shutter speeds 
Focusing, of course, is still a nightmare with reverse macro... but burst mode is your friend 
Focusing, of course, is still a nightmare with reverse macro... but burst mode is your friend SO! With nothing more than a basic (reversed) kit lens and a little spontaneous ingenuity, you can produce results like this:
Microscope-like quality from nothing more than a basic DSLR and a kit lens. So glad I can finally achieve the detail I've been looking for in my snowflake shots! The symmetrical bubbles inside the snowflakes is absolutely mesmerizing and is becoming an unhealthy obsession
Anyway! Just thought I'd throw you an update on what I was up to. Lots of snowflake shots like the one above (cropped in) to post later. Will likely mess with colors/lighting the next time I get the chance to shoot what will hopefully be larger snowflakes If you haven't heard about the Reverse Macro Technique, check it out here! framedbynature.deviantart.com/…
Happy Friday, everybody!
