Dozen Clock
Read full descriptionHide full description
Dozen Clock shows the time in a different way than other clocks and watches. In digital and analog format, too. It enables the user to have a tricky but still precise display of time enabling perhaps new ideas to root and grow. Released currently exclusively for Apple products, the application is able to display the date also in the format according to the Japanese calendar. INSTRUCTIONS: The biggest rectangle in the middle shows the minutes ( numbers outside the circle ). The small rectangle in the middle shows the hour ( darker numbers inside the circle ). The small red rectangle in the middle shows the seconds ( no numbers since it functions like in normal clocks ). "Think different." - Steve Jobs
Sea Levels App
Read full descriptionHide full description
We focus on how rising seas could affect local communities, landmarks, and coastlines under an extreme sea-level rise scenario, used to plan the construction of the Thames Barrier in London, UK. Using publicly available elevation data, our app provides a simple interface so everyone β from students to planners β can better understand coastal innundation risks. This knowledge can help communities prepare, adapt, and make informed decisions about the future. While the app is not meant to replace formal flood defense studies, itβs an easyβtoβuse educational tool to see the big picture of potential climate change impacts on sea levels.
