Inspired by this, I decided to try my hand at making some melted styrene Chaos terrain to accompany my in progress Nurgle army. I simply put some random chunks of styrene (of the thick blue insulation variety) onto a CD base and sprayed with a generic cheap black spray. The first attempt was a failure. I used too much spray and the foam just melted into a puddle. The second attempt I didn't spray as much paint and it worked like a charm. I used the end of an old brush to pull some of the molten foam around, which resulted in the stringy gooey look of it. I made some milliput balls of varying sizes for eyeballs and stuck them into the foam, along with a few arms and things from the bitz box. Once dry I painted it. I tried to go for a fleshy sort of look to parts of it, while other parts are just a toxic green mess of disgustingness. The camera flash makes the colours look a tad different. The puddles of toxic goo appear yellow in the pictures, but are actually a bright toxic green in real life. I added some clear shiny nail polish to the eyes and the puddles of goo to give them a sheen, which doesn't really show up in the pictures.
This was an easy and fun project, and I am very pleased with the results. It reminds me of early 90's death metal album colours, which seems fitting for Chaos.
Also note my first squad of Dark Angels making an appearance.
