For the PA love of your life: the AV tee
If your significant other is a PA or home audio/cinema nut, then you could do worse than buy them this audio-visual tee-shirt from Threadless.
On the back of the shirt we have all the standard connectors you could want, from the (nearly) bygone SCART and S-VIDEO through to HDMI and digital inputs/outputs.
On the front, simply a standby button and a phones jack.
Sadly, this is just a printed shirt, with no working or moving parts (other than the human body wearing it, of course). I’m surprised it doesn’t come in an iPod version.
