From Sidekick Books:
"Aquanauts was the first in our Headbooks series: a set of interactive, highly visual complete-me-yourself books aimed at taking poetry out of one corner and inviting readers to become collaborators. To launch Aquanauts, we joined forces with live artist and poet Abi Palmer to host Aquanautica, a deep dive into a post-flood world. Participants followed the signal of the mysterious Captain Nautilla to find a cavern of merbartenders, scientists, sirens, signs, sceptics and sculptures."
