I am sad to say I missed them, but luckily, others were inworld to greet the Japanese television crew from SLTV who shot a live hour-long broadcast featuring CDS.
My thanks to Vic who told me they had come, and to Cleo who gave me the link to the program:
I wrote them a notecard back and had it machine translated into Japanese - hopefully I haven't offered them Jupiterean lobsters with mango chutney but instead have successfully managed to let them know how pleased and honored CDS is about this.
