Visualising Air-Flow With Cat Hair

When your PC case's mesh filter becomes an unintentional computational fluid dynamics visualization tool. The cat hair has perfectly mapped out the intake airflow pattern, creating what looks like streamlines you'd see in a CFD simulation. It's basically free thermal analysis – you can literally see where your cooling is working and where it's not. Your GPU is probably thermal throttling while simultaneously conducting groundbreaking research in particle flow dynamics. Who needs fancy RGB fans when you've got organic fiber-based airflow indicators? Just tell people you're running real-time physics simulations on particulate matter distribution. The dust filter is doing exactly what it's supposed to do... it's just also creating modern art in the process.
