I don't know about Trek Tech, but there are often Trek Art threads based on the literature. For instance, there was a thread last year in which various people were offering designs for Cleopatra's Needle from my The Buried Age, though that's sadly gone dormant. And I've seen Aventine threads there too.
Hoping to get back to the Cleopatra's Needle project at some point sooner than later. Been busy of late with other things, including artwork for a couple of comics projects that should see print in a couple of months. Details on those projects in the appropriate branch forum here when they're ready.
Got this issue late...WOW, a fairly comprehensive article with lots of new visual concepts and artwork of the Aventine, plus a pull-out. What a beautiful ship! Highly recommend this issue...or get the online version.. https://www.zinio.com/checkout/publisher/?productId=500451061&offer=500242183&rf=tx-titanstm RAMA
