```rust
let image = tinygif::Gif::::from_slice(include_bytes!("../../cat.gif")).unwrap();
loop {
for frame in image.frames() {
let start = Instant::now();
frame.draw(&mut display.translated(Point::new(10, 80))).unwrap();
let elapsed = start.elapsed().as_millis();
info!("draw {}ms", elapsed);

let delay_ms = (frame.delay_centis * 10) as u64;
info!("delay {}", delay_ms);
if delay_ms > elapsed {
Timer::after(Duration::from_millis((delay_ms - elapsed) as u64)).await;
}
}
}
