Hey timmse 
Thank you for the warm welcome!
I accidentally created a duplicate (kind of) of this thread here
which is why I flagged this one so it could be closed.
I already received some very helpful feedback in that other thread which helped me understand the differences between that filter that´s being used on the “infinitemonkeys” website and the new filter from Bricks that´s being worked on.
I just checked the member you linked in your post and I couldn´t trust my eyes! 
It´s actually THE Eric Embacher as it looks like to whom I already wrote from my mail account! He already gave me the hint in the mail that they´re working with the “Isotrope JS” plugin. What a coincidence to meet him here again! I´ll definitely have to try implementing it into a website I create with Bricks!
However, from what I´ve read on the other forum thread it´s probably better to use actual AJAX filtering for most of my use cases.
I´ve got just one tiny offtopic question I´d like to ask (although I know that this doesn´t belong here):
I couldn´t find any information about where Bricks (as a company?!) is actually located. Under a YouTube video I read that a user wrote that you´re from Germany? Is that correct?
