Paniponi Dash!, Hidamari Sketch Recommendations
Created by the same person and produced by SHAFT. Hidamari has a few references to Pani Poni Dash as well.
Both shows are from Studio SHAFT and directed by Akiyuki Shinbou. The animation style used for both shows is incredibly similar, even though Hidamari Sketch uses a more simplistic art style overall. Also, I noticed that a few characters share similar quirks with characters from Pani Poni Dash! (Miyako reminds me a bit of Himeko and Sae somewhat resenbles Rei).
Both by the same people. Paniponi Dash is insane, while Hidamari Sketch is sweet.
