This has to be one of the most fun things I’ve seen with WebAssembly, a falling sand simulator! You can choose from a wide range of materials, add fire, wind, lava, etc… It’s great fun creating structures then burning, or blowing them apart. The game also works very well on mobile devices. Once you get bored playing with the game, head over to GitHub for the sourcecode.
There are now a wide number of standalone WebAssembly Virtual Machines to choose from, including Asmble, wasmer, WAVM, life, wasmi and wagon. These have been created for various reasons, some are hobby projects, other power blockchain or serverless projects. This article compares the performance of these VMs using a variety of benchmarks, declaring WAVM the winner.
