Last weekend we went to showcase O;T at a Swansea (Wales UK) hackspace ran event. It was very good to get feedback from the general public.
It was great to see the reactions when pointing out that nixie tubes are made up of layers. I guess there isnt anything like that anymore with flat "modern" displays.
Having the prototype was great, the best was probably, and I quote:
""How did you fit all this into there?""
Thank Swansea Hackspace for having us!
