Progress, and a see-through house

Did a little more work on the "pipes" maze. Felt a little easier to link them together, which is exciting in its own way.

Glancing through an architectural magazine this evening I saw a "see-through" house (only good for warm & dry climates, obviously). I sketched it from memory, then thought "what if I have a mouse digging around in the walls?" Could turn into something interesting.
