Our goal with Alice 5 was to create our own shader core and supporting hardware and software to download and display ShaderToy projects. We explored and understood to various degrees:

1. ShaderToy shaders and structures
2. Shader parsing using glslang to SPIR-V
3. Shader compilation using software written from scratch
4. RISC-V instruction set as a GPU shader core framework
