Something to enjoy with Catriona. “Focusing on building actual models with real bricks, The Unofficial LEGO Builder’s Guide comes with complete instructions to build several cool models but also encourages you to use your imagination to create your own fantastic creations.” Catriona and I love building things with Lego’s, things she promptly destroys soon afterward only to begin the process anew. We might find some inspiration from this book. It’s a good example of being creative within constraints too!
