Digital Little Tree

"Stuck in your office job dreaming of the open road?
A real car air freshener would only upset your deskmate?
Your truck simulator setup is missing that final, immersive touch?"

Here’s your digital trucker dream come true.

This project brings a classic tree-shaped air freshener to life – with a digital twist: rotating images, temperature display, and customizable brightness, all inside a fun and functional desk accessory.
