This wallpaper from the talented pixiv illustrator, Hirokawa 「広川浩一郎」 , is so awesome that I have had to stick it up as a main article.
Featuring the whole cast of K-ON! moeblob girls in their own 2 piece swimsuit wear, the wallpaper may be more on the ero-scale than moe. They seem to have rather biggu eyes. Biggu 「 ビッグ」means big in Japanese.
I believe many who have visited Sankaku Complex recently would have seen the funny Daler Mehndi music video spoof. Those who have not should give it a peek. It’s absolutely hilarious!
