Crowd Supply has a development underway using an ESP32-S2 called MorphESP (an ESP32-S2 240 w/ 240 x 240 ST7789 color display for $39). 21 days left before project closes. The developer is from Orleans, France ( Philippe C. ).

"...small, vintage style, nixie-like table clock with four morphESP240s talking to each other using ESPNOW MESH.>
The reason I bring this up is a project application he will post on his GitHub soon using a Nixie image on each color display -- attached are some project renderings.
