Not as exciting as many others, but I always have a soft spot for the old centralised/decentralised/distributed systems diagram: https://www.researchgate.net/profile/Christopher-Ehmke-2/publication/334170377/figure/fig2/AS:776214553821186@1562075379877/Distinction-between-centralized-decentralized-and-distributed-systems-according-to-Baran.ppm https://www.researchgate.net/profile/Christopher-Ehmke-2/pub...

Plus I always thought aesthetically it looks lovely, like it'd make a good tattoo.
