This month's issue of Knit.1 has a Tunisian crochet pillow; it's a peacock feather intarsia.
Crochet Pattern Central has some Tunisian crochet patterns: http://www.crochetpatterncentral.com/directory/tunisian_crochet.php . Just doesn't seem like there are many patterns out there for it.
You're probably going to have the most luck searching for afghan or tunisian crochet, but you might try looking for tricot crochet, railroad knitting, and shepherd's knitting too.
Oh! And the current issue of Crochet Today has a Tunisian bag pattern, with a rose cross-stitched on to it too.
