The WASM Bus for using WebGL on tokera.sh
```rust use wasmbuswebgl::prelude::*;
fn main() -> Result<(), WebGlError> { let context = WebGl::new()?;
context.clear_color(0.0, 0.0, 0.4, 1.0);
context.clear(BufferBit::Color);
std::thread::sleep(std::time::Duration::from_secs(4));
Ok(())
} ```
You can test your WASI program by uploading it to wapm.io and then heading over to the Tokera Shell
