Pori, the Love Sponge is one of the harlots in "The House of Hellish Harlots". The public demo of that has been updated to v0.025 and can be played here. Here is a lovely pic of her, showing her in all her comfy loveliness.
While I'd love to say I was responsible for this, the piece was independently commissioned by Mark45 and he kindly gave me permission to share it.
The artist is HunggryCroissant and more of their work can be found here.
I like this. If I was to add art to HoHH it would be through profile pictures like this. The ideal GUI for HoHH would likely take the form of a book with artwork on the left page and the text on the right. Unfortunately, I lack the wherewithal to create this, so the project will likely stay text-only for the moment. What I did think of doing was to create a profile page on houseofhellishharlots.com and list all the harlots with profile pics and details (Kind of like Monster Girl Encyclopaedia, but if all the monster girls were offering services in a massage parlour/brothel). Art like this would be perfect for that.
