Rehousing my neon nixie-flowers in a glass dome.

Almost 20 years ago I was doing some experimentation with making decorative flowers out of neon lamps. I did two versions. One with a resistor per neon so they all lit, and one with a bit of circuitry to try and create a random effect where the light moved between the flowers petals. It requires all matching neon lamps from the same batch for the best results.
In this video I put them into a repurposed glass dome base to protect them from dust and damage, and also to protect inquisitive fingers, since they operate at mains voltage.
Note that this circuit is running at 240V so if you want to try the same thing with 110V you will need to swap the 470K resistor for something much lower like 100K.

The circuit is very sensitive to ambient light and electrical fields. When first powered up a single neon may light, but when left running continually it will gradually evolve. Power consumption for several flowers is a fraction of a watt.
