blurhah、最初のバイトで縦横のピクセル数を1から9まで選べるっぽい。9x9ピクセルでやばい画像を作れるかチャレンジだ!

最初のバイトじゃなくて最初の1文字をbase83でデコードした結果だ。base83で1文字だと0から82までの数字をエンコードできるのかしら。
@zundan @unarist Ask me anything about blurhash!
@Gargron @unarist We're currently just having fun looking into how the hash is expanded to the image! We might ask you weird questions later :D
