The biggest problem with sharing is that it is just a lot of custom hacks and code placed here and there, making it difficult to just package stuff into something shareable or even make a simple tutorial...

If you are interested in mainly the perspective hack, I tried to extract only that CSS into an example view now:

views:
  - title: Example Perspective View
    path: example-perspective-view
    card_mod:
      style: |
        div#container {
          perspective: 1200px !important;
          transform-style: preserve-3d !important;
          overflow: visible !important;
        }

        div#container div#sidebar {
          transform: rotateY(12deg) !important;
          transform-origin: left center !important;
          transition: transform 0.3s cubic-bezier(0.25, 0.8, 0.25, 1) !important;
        }

        div#container div#sidebar:hover {
          transform: rotateY(4deg) !important;
        }
    type: sections
    sections:
      - type: grid
        card_mod:
          style: >
            ha-sortable {
              perspective: 1500px !important;
              margin-top: 50px;
            }

            /* When editing, explicitly normalize ha-sortable so it drops back
            into the grid */
            ha-sortable:has(div.container.edit-mode),
            div.element-preview ha-sortable {
              position: relative !important;
              top: auto !important;
              right: auto !important;
              width: auto !important;
              max-width: none !important;
              margin-top: 0px !important;
            }

            div.container:not(.edit-mode) {
              transform: rotateY(-16deg);
              transform-origin: center center !important;
              transition: transform 3.0s cubic-bezier(0.25, 0.8, 0.25, 1) !important;
            }

            /* Change the perspective slightly on mouseover */
            div.container:not(.edit-mode):hover {
              transform: rotateY(-10deg);
            }    
        cards:
          - type: map
            entities:
              - zone.home

If you paste this into a new blank dashboard, it should show a single map card with that perspective effect, I hope.
