I got no affiliation with these people, but thought I would post just to help out people here that might be looking for something different.
Browsing ebay I ran across two sellers.
Who states in his listings:
" Please ask if you have any questions or are interested in any other specific custom lava lamp. Commission custom lamps available upon request. "
This guy appears to hand build custom lava style lamps.
From one of his listings
"Tallboy cylindrical dynamic lava lamp hand made to order. 23.5 inches tall and 4 inches in diameter. Comes with everything needed including light bulb. Lava color is Neon Yellow Orange with a black base.
Lava and base colors can be changed on request.
Lamp ships with no water, buyer fills with distilled water and adds the chemicals I send with it. "
I'll reach out to them and see if they would like to join the community
Yes, I have seen both sellers items on ebay many times. Both seem to do nice work from what I can see in the photos.
