Photo of progress so far

Here's the habitat(s), bolted down to the platform (the bolt heads cannot be seen as they're buried under a thin layer of cat litter) and joined by acrylic tunnels that are now sealed against water using silicone gel, which has hardened nicely overnight. I've just added the air input tubes, which will connect to the detachable umbilical once *their* silicone sealant has dried.
As you can see I've included the Hampture Mk.II habitat alongside it for size comparison, and I've been positioning the camera in different places and looking through it wiht my laptop to get a sense of where the best view would be.
