One of the biggest problems with the Raspberry Pi is, arguably, cable management.
With cables seemingly coming out on every side of the Raspberry Pi, in no time you can end up with a "rats nest" of cables and a serious cable management problem!
Here is a simple solution that requires just two things:-
1. Right angled cables or adapters
2. A slightly modified "life jacket" style connector (known as a "three pronged clasp")
Here is a larger photograph of the finished solution with all the cables neatly routed to one side of the Pi (the HDMI adapter shown is larger than strictly desirable and I am still on the lookout for a compact right angle HDMI cable - without a swivel end - that can be incorporated into the same neat bundle).
