How about the matrix film theme for pi-hole. It would look cool.
And has anyone noticed that when you are using pi-hole to protect your lan only and not wan, as the pi-hole is the dns of your lan that through wifi on your guest network that the ads of apps on your phone are not blocked but when your on the administration wifi that, the ads of apps are blocked? Please fix this pi-hole.net
This is not a Pi-hole issue. The problem lies in the router. On most routers, clients on the guest network are completely segregated from any clients on your protected network. As a result, clients on the guest network can't see the Pi-hole on your protected network.
