I was hoping to find some suggestions for tiny servos to use with a miniature mechatronics project that I want to attempt (will be controlled by a TinyDuino).
Is anyone aware of ultra-tiny servos, or perhaps might have other ideas for miniature robotics? They don't need to be all that powerful.

You can try some of these:

I picked up some servos from them but haven't had the time to try them out.

The Cirrus CS-3 Micro Joule Servo (http://media.globalhobby.com/manual1/443435.PDF) is pretty small... slender and long, which could be great to stack back to back under a TinyDuino Stack. It is 20.1L x 6.1W x 6.1H mm but $50/ea according to servodatabase.com (http://www.servodatabase.com/servo/cirrus/cs-3)
For simple steering or actuation, Plantraco has some wonderfully small components. The starter set has a very small receiver and 2 MiniAct magnetic actuators, among other things. Microflight sells a The Deluxe Starter Set (http://www.microflight.com/Online-Catalog/Radio-Systems/Deluxe-Starter-Set-1) for $99. Microflight separately sells the MicroAct Magnetic Actuator (http://www.microflight.com/Online-Catalog/Actuators-and-Servos/MicroAct-Magnetic-Actuator-0-4g) for $7/ea and the MiniAct Magnetic Actuator (http://www.microflight.com/Online-Catalog/Actuators-and-Servos/MiniAct-Magnetic-Actuator-1-1g) for $7/ea. Here is a cool video (http://www.microflight.com/MicroScout-Assembly-04) about the MiniAct Actuator. They also have a nice tiny motor and gearbox (http://www.microflight.com/Online-Catalog/Motors) selection. For a really tiny actuator, there is the NanoAct-Actuator (http://www.microflight.com/NanoAct-Actuator-Kit).
The Ping Zheng 1.3G Servo without PCB PZ-15319A (http://pzservos.en.alibaba.com/product/761938548-218333323/PZ_1_3g_Servo_Lightest_Servo_for_RC_Toys.html) is 12.6L x 6.2W x 10.3H mm.
Nanomotion's EDGE miniature Piezo Motors (http://www.nanomotion.com/index.aspx?id=2576&itemID=1456) are small. Providing unlimited linear or rotary motion, the EDGE motor uses compact ASIC-based driver, and can be operated with any servo controller. It is 13.5L x 7.6W x 3.15H mm.
