Anyone seen this before? My neighbors tree has these odd, hard nodules
forming on most of the leaves of his oak tree. A Google search came up bare,
but I'm not sure what to search for anyway. It seems to drop bunches of
leaves all summer, still connected to twigs. Otherwise looks healthy.

Gall seems to be the proper term. There are several different causes but
many are from insects injecting their eggs between the layers of the
leaf which then develop there causing the odd growth. I'd try slicing
some open with a super sharp blade and then inspecting the innards with
a magnifying lens. If you seen little grubs then you have a good idea
what is going on. A Google for "oak leaf gall" (without the quotes of
course) will give you page after page of reading material that may pertain.

Large, round growths are oak galls, caused by the larva of a tiny
wasp. It irritates the leaf tissues, causing the gall to form.
Inside, it's somewhat corky. Older galls show small holes through
which the mature wasp exits. These are generally harmless to the
tree. In colonial times, settlers would gather the galls and boil
them to extract the tannic acid, which they would then use to tan
leather, set dyes in yarn, and make ink.

It's quite common for an oak tree to shed leaves in bunches, still
attached to twigs. However, if the tree is being defoliated, then
there is likely some insect causing damage. Such damage two or
three years in a row can severely injure or even kill the tree.
Since a mature oak can be quite valuable, it's worth the price to
have a professional treat the tree to stop such insects.

Nothing special about that tile. Self stick, probably got it at Home Depot.
It replaces some lame mousepad type thing that came with the rolltop desk.

Don't you ever look at what's in the background?
Like in movies, I love to look at what is in the backgrounds. People,
stuff.. I find it infinitely enlightening.

I have this friend that sends me pictures of her garden. I ALWAYS look at
what is in the background .....
I get some hella cool ideas for things like tomato cages and garden layout.

*snikker*

*jaw dropping and hitting the deaktop*
THUNK

I thought it was a creamic or stone tile.
*sigh*
