Photos to scan
Some pictures I've taken that I intend to add as soon as I can use a friend's scanner:
 * Cranes:
 * International Crane Foundation, http://www.savingcranes.org/
 * Black-crowned Crane
 * Blue Crane
 * Common Crane (aka Eurasian Crane)
 * Red-crowned Crane
 * Whooping Crane
 * Panavia Tornado (The pictures are rather low quality, but do include views with wings extended and retracted.)
 * F-117 Nighthawk
 * Aerial refueling
 * Stonehenge (already has a few pictures, I might just skip it.)
 * Bath, England
 * Oxford, England / J. R. R. Tolkien
 * Yak if it doesn't already have one
 * Oh bloody, I'm going to have to write the article too, aren't I? Unfortunately, I don't know Yak....
 * Image:H-R diagram.png Not an actual photo to scan, but a diagram that could use some tweaking

WikiProject Astronomical objects

 * Perhaps to add to the astronomical body infoboxes in "Observational data" or something like that:
 * Surface brightness
 * Range of apparent magnitude (for Solar System bodies)
 * Range of angular size and/or angular area (for Solar System bodies)
 * Maximum elongation (for bodies with orbits entirely within Earth's)
 * Possibly move from other sections: albedo, absolute magnitude (planetary meaning, for Solar System bodies)

Pages I just like

 * Orders of magnitude
 * Orders of magnitude/template
 * Various physics and math topics:
 * Barycenter
 * Derivative
 * Table of derivatives
 * Table of integrals
 * Escape velocity
 * Gravitational constant
 * Orbit
 * Orbital elements
 * Orbital speed
 * Synodic period
 * Rouse History of Mathematics
 * List of Latin phrases

Possible future pet projects

 * Babylon 5 & related
 * $$\delta v = v_{exhaust} \cdot ln \left( {m_0 \over m_0 - m_F} \right) $$
 * $$m_0$$ is total original mass, $$m_F$$ is mass of fuel consumed
 * What's the appropriate article for this one?

Orbital
