Hey there,
Looks like a nice community to participate in !
I wanted to chime in and share a bit of my work. 
So the “Exedre” project is a little UE4 scene where I plan to focus on a lot things, including a bit of real-time VFX. The goal is to have fun, practice a bit to not get too old and of course try new things (like ray-marching at some point I hope) !
(What follow is months of work during my free time.)
So initially I started by looking into simulating a glitchy terminal window. So I had to look into using custom render-target for writing things, which I have never used did before. After a bit of setup I got it working, and from there I looked into using a second buffer to accumulate information :
I went much further on the glitches and implemented some logic, here is a video of the result :
Now that I had the terminal, I built the computer and linked the keyboard to the terminal, giving this :
I must admit I’m quite glad of the end result, I was able to achieve a lot of things and had a lot of happy accidents while iterating on that.
Now that the compute ris done I’m working toward the rest of the scene, investigating some holograms :
I’m also experimenting some other type of interface, like this old-school loading screen :
Let me know what you think !
