There was one at Fragapalooza... he took UV market and drew on every single trace. Hit with UV tube lights of the era and it had a defineite radioactive glow but in a very interesting way since visually basically every trace popped. Always liked the effect... no way I'd ever have the patience to execute it.If there's one thing where window cases have helped it's motherboard appearances. They may shatter, but glass side panels being mainstream meant no more radioactive or baby barf PCBs as the norm.
