Seems the C'thu have been pretty popular. The Kickstarter campaign for the new Relics faction has been making their way through various stretch goals. As such, there's quite a lot that's been made available as add-ons for the campaign. If you value your sanity, you might not want to click through.
As you can see, there's plenty more madness available. There's also a bunch of freebies that've been added to the campaign, such as a set of dice (they don't have photos of the dice yet to show off, sadly, because I love dice). For those that have been curious, there's also an update where they show off a size-comparison with the unlocked figures.
If you want in, there's still 19 days to do so.
