We in Australia do not have a religious government, and your information about the children's programme 'Fat Cat and Friends' is completely wrong. Check out:
Back in 2003, I ran a Software RAID5 setup under Redhat 8.0 which I later scrapped.
The server had four Seagate Barracuda IV 80Gb drives (RAID optimised versions) connected to a Highpoint Rocketraid 404 controller. The system was a dual Athlon SMP configuration on an ASUS A7M266-D SMP motherboard. The system had 512MB of registered DDR ECC memory
When extracting large tarballs, I would often experience CRC errors at random points within the archive.
When I compared the copy of the archive on the RAID5 filesystem with an original copy, I found differences. This really freaked me out as it may have meant that errors were being randomly introduced into newly written files.
The problem disappeared when I manually disconnected one of the drives, placing the array in degraded mode, and then recopied the original archive.
This led me to suspect that the authors of the RAID5 code in the kernel did not get the implementation of the read/reconstruction algorithm quite right or that the code had nolt been tested properly under SMP configurations. I did not have time (or the patience) to investigate this further.
I abandoned RAID5 and switched to a nested software RAID-1+0 configuration. It works, but I had a bad experience reconstructing the array when one the drives gradually started failing.
Fortunately, my workplace has set aside some money to replace this machine with a new Dell server with inbuilt hardware RAID5 and hot-swappable drive enclosures.
My final advice is: if you have the money, don't settle for second best.
The displays used in the Virtual Boy were OEM versions of Reflection Technology's Private Eye.
These were LED-based and used a vibrating mirror to create the image. I assume that as red LED's were much, much cheaper than other colours at the time the virtual boy was made, that was why they used them.
Here is a link to detailed info on the head-up displays used in the Virtual Boy.

Are you talking about America or Australia?

1. Fat Cat did wear clothes
2. It was removed because it wasn't educational (I don't know anyone who would argue with that)
I am not aware of that specific BBC documentary, but I have never come across pixellated science documentaries on Australian TV.
