Ok man... here we go I got a plan for you. You should build a time machine and you could go into the future and spend that $50 on some trees when they were available...
The Plan
You need
The Time Machine
Take the money you have NOW for the trees and place it in an envelope, and put the envelope somewhere safe. You will be taking this envelope into the future with you. Now, take all the other stuff and go build a time machine.
One of the two things will happen
The way I see it, its a win win.

I use these for photography, they're fun.
I think any should do. Here is the one I have.
This is a picture I got with it.
One more.

Wow, I love the enthusiasm, thanks for asking! Most of this shot was done entirely in-camera. I'm covering the top-right of the frame with a triangular-prism-shaped crystal. The crystal gives off reflections and is also causing that rainbow-colored fringing. In the top-most-right you can see the street scene reflected with the aforementioned fringing and the bottom right you're actually seeing the reflection of the blinds that this image was shot through. DoF was narrow enough that you cannot actually see them in the bottom left of the image. You can also see a third reflection of the street scene in the middle of the image reflected and rotated 90-degrees to the left.
Happy to answer any other questions you have!
P.S. Here's the crystal I was using if I didn't describe it well enough.
These are also what a photographer uses for that rainbow effect you've been seeing on a model's face in portraits. Seen here
There are cheaper ones (this one is $20, I got the $8 one) but here's a link if y'all are interested. The pyramid one looks pretty cool too

How about $7.44 for one at Amazon
Or a pack of 5 for $10.38 also from Amazon
Edit: 48mm is a very odd diameter for a non-custom lens. You are much more likely to find 50mm, 100mm, 200mm.
Also focal lengths will be limited selection, but 100mm is easily found if that will work for you.
At the time when I was first ordering, the link that Google provided was sold out so I searched amazon for an alternative. I don't know anything about lenses though, and I didn't realize double convex and bi-convex were not the same thing.. so I ended up with these: http://www.amazon.com/gp/aw/d/B00BIKGMZ8 . In addition to not being the correct style of lens, they're also too big (50mm diameter instead of the 25mm they are supposed to be. )

Or you can just not believe in fairy tales and skip that part and enjoy the smell.
Bonus spectrum fun: Diffraction grating glasses. Now everything is rainbows. You'll be shitting unicorns in no time.
It's a concave optical lens from Amazon. They're quite cheap and work great!
From what I've seen, the two main focal lengths used are 15mm and 20mm but I can't remember off the top of my head which one is more shallow.

U dont need software, buy a prism https://www.amazon.com/Amlong-Crystal-Triangular-Teaching-Spectrum/dp/B00FHFV9AI
Search youtube vids how to use prism to get the same effect
The official cardboard lenses are 30mm biconvex lenses with a focal length of 45mm. If you cant see the edges of the screen (I cant) you could swap larger lenses with the same focal length to get a better field of view.
Maybe these would work? A cardboard shim might be needed since the focal length is 50mm.

You can buy a prism that splits the light out into its component spectra. The Edmunds Scientific catalog might offer something like that. You'll be able to see where the peaks and the gaps are, but not how high or low.
Found this on Amazon.
Thank you for your kind words! I wish there was more to explain, but I purchased a prism like this one Pangda 6 Inches Optical Glass Triangular Prism Rainbow Maker for Science Experiments Teaching Light https://www.amazon.com/dp/B0789JHY8P/ref=cm_sw_r_cp_apa_ADtVAbE97XMW7 and held it up to the lens to reflect the neon lights inside the window to acheive the effect.
this would be better, you want a minimum of 34mm diameter. Longer focal length shows more of the screen.

I think I was over complicating things. I ended up ordering this and this and I'll just see how it works
Lady, please add this one instead (this is the one I have and I love it) https://www.amazon.com/Triangular-Refactor-Teaching-Spectrum-Photography/dp/B07GNX2W9F/ref=sr_1_16?keywords=light+prism&qid=1550630608&s=gateway&sr=8-16
I went with these:

I got the Finebest version which is an unbranded Z3. It was Saturday free shipping prime.

So, fingers crossed that everything works out well. :)

Looks like they're designed for classrooms. There are other packs about the same price with different selections.
Their super cheap on Amazon
I'd like a larger one myself. Maybe double this size. But it works really well. My best time is around 14 minutes on this surface untreated. If that helps at all. Enjoy it man. I love mine.
Edit: Here is a pic for size comparison. I don't know why I'm telling you all this. I guess I would've wanted to know when I was looking around.
What a deal!
Probably something like this, very popular prop in photography.
The other day in another thread someone linked to a video explaining how to use different prisms and reflectors for this kind of effect.
rotate it in front of the lens to create unique reflections and flares!

United Scientific LCV108 Glass Double Convex Lens, 100mm Diameter, 200mm Focal Length https://www.amazon.com/dp/B00ES3U5LY/ref=cm_sw_r_cp_api_i_M2B3Db4K713H0
I found this on Amazon with a simple google search. It looks like it’s 100mm in diameter, but this was my second result so a smaller one can’t be that hard to source. All planoconvex really means is that one side of the lens is flat and the other side is convex.
Next step is figuring out what lens to buy.
Assuming a 5" screen size, Google calls for lenses with a 25mm diameter and a 40mm focal length. With a bigger screen, you might be able to work with 38mm/50mm lenses, but I'm not sure. I'd probably just try and get my hands on the regular lenses first to see if they can work on your Note 3. You may have to engineer a second revision of your headset to get it perfect.
