Well, recently I've finished Moyashimon, Mononoke (not to be confused with Princess Mononoke), and Oh Edo Rocket.
Moyashimon was a cute show. Slice of life show about a guy with the ability to see bacteria as chibi doodles who goes to college at an agricultural university. Has some science lessons about how bacteria is used in food production, like fermentation and brewing alcohol.

Mononoke is a horror/psychological show following the nameless medicine seller from Bakeneko (a stand alone arc that is part of the Ayakashi classic Japanese horror anthology) as he exorcises ghosts by exposing the reason of their haunting. The series is probably best known for its unusual visual style. It imitates the art style and texture of traditional Japanese paintings sort of like Okami... But on LSD. As you can probably see from the OP

Oh Edo Rocket was a bit of a disappointment for me. I liked the background art (again reminded me of Okami), but disliked a lot of the character designs. And I disliked some of the plot points, especially the whole subplot with Akai because I hated his character and didn't like how the show wanted you to sympathise with him despite his actions. Some of the fourth wall breaking moments and modern anime references or anachronisms were funny though.
