We have 5 people interviewing for a tech job, I've suggested that we have a "What is it" question with some small random bits of hardware.
I currently have:
a linksys 1000baseSX mini gbic module
a POE injector
a firewire 800 cable
a smart senteo reciever.
What other common, but slightly obscure things can we think of... bear in mind i'm trying to obscure but not cruel
