I have a few ideas...

Ashtrays, overflowing with ash and ciggie buts.
Bookshelves with half the books lop-sided or fallen over (and irrelevant gaps).
Stacks of CDs that are about to topple over.
Stacks of books, ditto.
Sinks/washbasins with grimy soap stains (texture add-on..)
Paper Coke (or other) drinks (the ones with the plastic top with a straw in the middle.
Polystyrene (yellowish) take-away burger boxes.
Squashed fag-ends and Squashed chewing-gum (for pavement/sidewalk application and stick-to). Again these could be textures.
Discarded, 1/2-eaten meals (chicken bits, burgers, kebabs, chips etc)
Broken bottles.
Broken glass shards (usually found near bus shelters or phone boothes).

And as for the (1/2) Naked Vicky bit...
Drifted-in dead leaves. Clumps of moss and/or lichen. Stone steps with hollows in them where 1,000 years of feet have trod. Broken mosaic floors. Windows with traces of glass still there. Dead rodents.

errm - running out of time.....which reminds me:
Wristwatches that can be laid flat (the wrist-band stretched out) on a surface and the ends not clasped together (who wears a wristwatch to bed? OK, some do, but most take them off (after having undone the clasp/buckle) and drop them somewhere...

Not to mention clothes, ditto...

Anyone inspired yet??

Cheers,
Diolma
