Textures for Parallax Background

For all you artsy people that want to help out:

As many of you know, we are adding a parallax background for next release. Fot those of you who don't know that means, we basically have a couple layers of transparent background that move at varrying speeds as the player changes his position to create a parallax effect. Eventually, we want to create something like this:


Notice how the "front" layer moves a lot faster than the ones on the back.

Moving on. Current we have this background texture that I made tileable:


It already moves with the player, the only thing missing are the multiple layers that should be on top of it. I think around 2-3 should be ideal.

This post is a call to action to our artists out there. I need someone to create a couple textures that feature only the bubbles (not the blue background). These bubbles should be a whiteish grey just like in the one above, while the rest of the image should be alpha. The first layer should have bubbles the same size as the largest ones in the above texture (around twenty is fine). The subsequent two layers should feature larger bubbles, but in a smaller quantity (I'd say that the top most layer should have 5 bubbles double the size of the original image).



I know that my directions sound a bit restrictive and lack artistic creativity, so feel free to add your suggestions and we'll discuss them in this thread. Finally, this is a very important and difficult task, so its okay if you don't want to do it, but it would be really nice if someone stepped up to do it.



Thanks for reading this post, and helping us get the best possible background in Thrive!
