[Request] Stone-alien hybrid walls and gates

[vedrit]

I would like images and icons for the hybrid wall and gate for my mod. The style I'm going for is stone walls with alien tendrils growing out from and on the wall, taking inspiration from the style of the Infested Terran structures in StarCraft, only the alien parts looking similar to Factorio alien spawners.
The posts on the gates I want to look similar to the wall, but the gate itself will have a very chitinous look, and when it opens, it'll drop down similar to a regular gate, but it will also collapse on itself (I intend to have the hybrid gate have faster open-close speeds than vanilla gate)
Technologies for these will just be the icon for the item, and additional tech (for increased health-regen) will have healing-crosses in various sized, and a number in the bottom right corner.

I tried looking for some reference images, but being that I'm at work, I didn't spend much time searching and so didn't find any.
