How to replicate Thanatofenestra?

Thanatofenestra is a digital version of a Japanese Buddhist altar, designed as a single device. Modern urban living comes with limited space, making it difficult for people to maintain the tradition of praying to their deceased loved ones in some cultures. This device addresses that challenge by allowing users to display images of their loved ones. The images change with the candle flame, preserving the main components of traditional practices in a compact form to adapt to the current needs of users.
