        いつも先生の作る作品の色使いやパーツ選びやデザインなどがとても大好きです。あらためて言うまでもない事ですが、日本人を超えた芸術的な感性を生まれつきお持ちでいらっしゃるんですね。年齢も性別も国境も越えて先生の作品が評価を受けている事を最近ますます感動するようになりました。

        一日経ち、あらためてこの図を見ていたら、じっと見ているよりも、瞬きしながら見ると「♥」の部分がより膨張して見えました。スクロールした時や、スマホ端末を振りながらこの図を見ていたら、「♥」が揺れて見えました。本当に不思議ですね!👀✨👍

        example of brightness/hue altered of expansion switch effect with Dr Lit's metronome switch going off in two opposing directions per his studies of Pulfric effect. Evident aesthetics in ancient American color usage (or maybe back to 10000 years ago Japan ancient Civ).pic.twitter.com/TrndcciS3U
