OnePen is an application designed to alleviate the environmental problems resulting from Thailand's Loy Krathong Festival. Instead of releasing a physical krathong into the river, causing water pollution, OnePen guides users step-by-step to make a Thai cultural krathong in 3D, allowing them to design their unique one and see it placed in the real-world environment using AR technology.
With OnePen, people can participate in the Loy Krathong Festival and protect the environment!
