The main requirement was to create a user-friendly website to host and promote a 30-day UI design challenge focused on using physical-world analogies to inspire digital elements. The platform needed to clearly present each daily challenge, allow users to explore details of the tasks, and serve as a hub for designers to engage, share their work, and get inspired. It was also essential to encourage crowdsourcing by making it easy for participants to submit their designs and interact with the challenge community.
