If you worked on Lost Vikings I'd like to thank you for the entertainment during my childhood. Given your background did you ever get involved in the demo scene?
Consider a slower default rotation speed, esp. on your front page backdrop as you must be considerate of users with movement based nausea. Further consider generating a looping video for the backdrop on the hope page since it's a non-interactive element and could be optimized.
I'd like to thank everyone moving their hosting away from shared hosts to VPS.
Been on the same shared hosting platform for 15+ years and the hardware's load average dropped to ~16% on a 64-core Epyc /w 512gb RAM. Easily handles half million unique bursts without breaking a sweat.
I took it one step further even earlier using a Flash file as a backdrop which was able to achieve the glass effect while still being in a dynamic moveable frame. Can't recall if it used iframes, would need to dig up the code but considering the era it probably did.
