Is there any way to customize the background image effects?

I really love the refracted lines effect, but am curious whether it is possible to use custom CSS to accomplish the following:

1. Only have one slice, as opposed to multiple across the entire photo.
2. Specify the angle of the slice. 
3. Add an additional B&W effect on the refracted/sliced portion of the photo.

I'm sure I'm asking way too much of this feature, but I'm hoping someone with much more expertise could chime in.

Thanks in advance!

Hello!

Could you please share a url/link to your page with the background image effect. I'd be more than happy to help you where I can.

@Wolfsilon, thank you so much for offering to take a look! Really appreciate it.

I've also attached a mockup of what I'm trying to accomplish with the background image effect, so you can compare it to how it's currently functioning.

THANK YOU!

Hey, sorry.

I've tried to view the effects. I'm on a Mac but I can't see the effects being rendered at all. I assume these are effects/plugins from Will Myers? Prior to your response I was doing some research and couldn't see them on his examples either. I wish I could help but I've tried to view from Firefox, Chrome, and Safari with no luck. 😞

Bizarre! So you can't see the subtle parallax within each slice as you scroll? It looks like your browser needs to have something called WebGL capability, which apparently can be tested for here: https://get.webgl.org/

I've attached a screenshot of what this image effect option looks like within the site builder.

Regardless, appreciate you trying to help!
