A bright coloured fish??

I'm certainly not known for my love of the ID3v2 specification -- it is a terrible specification that I've had the displeasure of implementing.

However, I have finally found one redeeming quality of this specification. In section 4.15, while talking about the APIC tag, it lists the possible types of artwork that can be enumerated as part of the APIC tag:

$00 Other
$01 32x32 pixels 'file icon' (PNG only)
$02 Other file icon
$03 Cover (front)
$04 Cover (back)
$05 Leaflet page
$06 Media (e.g. lable side of CD)
$07 Lead artist/lead performer/soloist
       . . .
$11 A bright coloured fish
       . . .
$14 Publisher/Studio logotype

A bright coloured fish, eh?

Got any other cute specification bloopers/easter eggs?
