Spiral Vortex T-Shirt
Pull the plug in a bath and the water doesn't fall straight in: it swirls. This design shows exactly that, calculated rather than drawn. It combines two of the simplest flows in fluid dynamics: a sink, where water drains towards the centre, and a vortex, where it circles round it.
Put them together and every path the water follows becomes a logarithmic spiral, r = r₀e^(−(m/Γ)θ), crossing each line from the centre at the same angle. The closer the water gets to the middle, the faster it spins, which is why the centre glows brightest. The same shape echoes through whirlpools, hurricanes and spiral galaxies.
A hypnotic physics T-shirt in crisp white lines on a dark shirt, for anyone who's ever stared at the swirl going down the drain.
