A Portable, Wearable Green Screen?

I've been asked a few times to give some more information about my DIY portable green screen for video production. Which is actually kind of embarrassing due to the extreme primitive nature of its construction but heres the scoop:

I was slated to do the Google Summit Demo Slam, and I had decided that my topic would be color keying, since its my favorite WeVideo feature. I was trying to figure out a way to demonstrate how to use a green screen without actually having a green screen, or somehow make it work to setup a green screen within a 3-minute Demo Slam timeframe.

I considered a 3-fold science fair -type project board, but this would have still required me to have a surface (like a table) in which to set it on behind me. I decided to instead try and paint a standard piece of foam core with green paint. The original idea was that during the slam I could just hold it behind me and film via webcam, then demonstrate how to do color keying.

I painted 3-4 coats of acrylic paint on the board and let it dry. It did, unfortunately, warp the board a little bit, which was less than desirable. But the color looked pretty good, so I pushed forward.

I logged in to WeVideo and tried recording from my webcam while holding the board behind me, but it became obvious pretty quickly that there was no graceful (or steady) way to hold up the board behind me while filming. Frustrated, I explained the situation to a group of my 7th graders and asked them what they thought I should do. We started brainstorming ideas for mounting or hanging the board behind me (like, Can we attach it to a selfie stick somehow? How about putting it on a backpack? ), which inspired my very rudimentary solution: bend a couple of wire hangers into shoulder mounts and attach it to the foam core with tape!

If you look carefully, you can see the top of the hanger wire (you know, the hook part) underneath the tape.

This is what the final result ended up becoming: a curvy piece of painted foam core with haphazardly bent wire hangers as a shoulder mount. Embarrassingly primitive, but funny nonetheless, so I brought it with me to the GAFE Summit and used it as a prop in my Demo Slam. Fortunately, it got lots of laughs and attention, even if it didnt end up winning the competition.

I didnt actually USE the portable green screen contraption to film, as it still has some limitations:

Its not quite large enough to span the webcams view all the way to the edges of the frame.

The foam core only reaches to the top of my shoulders, making the green screen only useful for neck-up situations, which is limiting, to say the least.

Therefore, I have some ideas for improving upon my design for the future:

Buy colored foam core and skip the paint part, which would eliminate warping.

Use a larger piece of foam core, so it will cover the edges of the camera frame.

Attach a green piece of fabric to the bottom of the foam core, which would create a cape of green behind me, which would allow me to film from the waist-up (ish) and still have green background behind me.

Im not necessarily convinced that the portable green screen is better or easier than just toting a green fabric sheet around with me (thatd certainly be more compact!), but it does make for a great conversation piece! So there you have it. If you decide to make your own (probably improved!) version, please share it with me!
