Since Greek mythology explains the creations and stories of different Earth elements, numerous characters from Greek mythology were related to the body of water. Homer's Odyssey is a representative piece of literature that unfolds the adventure of Greek hero Odysseus. Calypso is a sea nymph who detained Odysseus for seven years, while Sirens are man-bird creatures who lure nearby sailors with their enchanting music to shipwreck on the rocky coast of their island. Poseidon is a famous god of the sea, and Kraken is a legendary sea monster of gigantic sized cephalopod-like creature that often appears in the Scandinavian folklore.

From the Greek mythological stories and characters, we gained the impression that underwater is often portrayed as a realm of curiosity, enchantment, and danger.

Adapting to the higher pressured deep ocean habitat, underwater organisms have unique body features that helps them survive better. Survival mechanisms similar to that of the land organisms like camouflage can be found amongst the underwater organisms as well, but they also have unique underwater features that are distinct to those in the land. Blobfish, for example, are well-known for their melting look after being pulled up rapidly by the fishers. However, they look totally different in their natural habitat, which is more than 3,000 feet below the sea level. Anglerfish are famous for their method of predation in the deep sea. They have bioluminescent lures protruding from their heads to attract prey to come near them. Prey fish would mistaken the lights and approach the anglerfish without being on alert. Humans also have mistaken a number of underwater organisms in the past, and mistaking manatees for mermaids is the most well-known fun fact introduced at the aquariums.

From researching various underwater organisms, we learned that misinterpretation is the repeating theme in both underwater survivalship and human understanding of deep ocean organisms.

Some of the famous mysteries around the world are related to the deep ocean. Bermuda Triangle, for instance, is a mythical section of the Atlantic Ocean roughly bounded by Miami, Bermuda and Puerto Rico. It is a notorious region where dozens of ships and airplanes have disappeared in the past. Atlantis is a fictional city mentioned in Plato's literature *Timaeus and Critias* that is well-known as the sunken city.

Underwater related mysteries gave us similar impression as the Greek mythology research, where the underwater has been portrayed as a place that's full of wonders and danger.

Since the exhibition would be held indoor on land, we had to find a way to recreate the underwater feel inside a building. Computer graphics and visual effects used in media often uses shots on land as the base footage, so we researched how the underwater scenes in movies depict the feel of water. Through the scenes from Harry Potter and Miss Peregrine's Home for Peculiar Children, we noticed that blue green tint, air bubbles, and water caustics are used to visually persuade the underwater scene. Billie Eilish's music video for Ilomilo is a moving image animation set in a deep ocean, which we gained the inspiration of sinking movement direction from.

For the interactivity aspect of the project, we also looked up how underwater themed games have designed their player experience. Some of the games we viewed are Subnautica, a survival game, Reveal the Deep, a short exploration game, Soma, a survival game with mini puzzles, and Lumione, an exploration game. Many of the games that gave immersive experience was developed in a first person shooter game style, where the user gains full control of what to see and where to go.

We first developed a overarching timeline together to set checkpoints as a smaller deadlines. Using the progress bar on the far right to indicate where in the timeline we're at, I kept track of individual works and the deadlines for other related documents that needs to be handed to others out of our team like the material purchase list.

We then tested the combined interaction content with the projector. Based on how we observed the content looked in the projection, we made a final color adjustment to express the hue and saturation we worked with on screen.
