- It seems like fans made a hand-drawn (colored) animation from Higurashi CD drama. It's a story about Keiichi-kun becoming a womanizer in Higurashi world.
- It's one of my favorite OPs of NHK documentaries. Song is written and performed by Adiemus. My other favorites are: "Century of Image (Image is from different show)" and "Road of Civilization". This is not from NHK, but "Kamigami no Uta" and "World Heritage (Image is photograph of Japan)"
