Visualising how close random GUIDs come to being the same
Guid Smash
The chances of generating two GUIDs that are the same is astronomically small.
The odds are 1 in 2^122 — that’s approximately 1 in 5,000,000,000,000,000,000,000,000,000,000,000,00.
Guid Smash visualises the unlikelihood by showing how close each new GUID comes to matching the target GUID.
At a rate of comparing 400,000 guids per second, Guid Smash should see an exact match within the next 421,000,000,000,000,000,000,000 years.
