I found a large colored glass vase at my local Goodwill for around $8. It's the perfect size for one large umbrella or a couple small ones.

To house the electronics and lights, I found a round mirror with a black plastic frame, also at the Goodwill. The mirror's interior diameter is just a bit too small to fit the vase neatly, but I can make it work with a little bit of maker ingenuity.

I removed the frame from the mirrored back, then cut through the side with a dremel. Then I heated the plastic frame gently with a heat gun until the whole thing was a bit soft and pliable, but not so much that it got melty. 

I plan to put the electronics inside the hollow frame, so I dremeled a channel at the back of the frame for my USB cable to pass.

I plugged in the USB cable and fit my Pico W inside the frame, securing it with some hot glue. I threaded the USB cable through the channel at the back and glued that in place as well.

Next I glued the pixels in place around the inner edge of the frame, right at the bottom. The silicone coating on these pixels is tricky to glue -- very few glues will stick to silicone. My favorite is Devcon Silicone Glue. It dries quickly, and clear-ish, and holds the silicone strip casing in place really well.

I left a few extra pixels at the end of my strip to illuminate Totoro.

I drilled a hole in the back of Totoro and slipped in the last few LEDs from my NeoPixel strip. The clear resin clouded up just enough to diffuse the lights perfectly. Glowing Totoro, Hooray!

I used some Thermoplastic and silicone glue to wedge him neatly into the gap in the base.

Finally, I used my Cricut vinyl cutter to cut out a silhouette image of Totoro that I found online. I fixed it to the glass vase using frisket to keep all the pieces in place. I love the combination of 3D and silhouette Totoro characters! The sticker really brings this design to life.
