The pgf manual isn't really explicit about it, so i'm here to ask it to the stack communauty.
I tried to put some shadow/blur effect around the spyonnode but with no effect at all !
I tried this :
\begin{tikzpicture}[spy using overlays={
circle,
magnification=2,
size=1.5cm,
connect spies,
Ggray1
}
]
...
\spy[circular drop shadow,
spy connection path={
\draw[thick] (tikzspyonnode) -- (tikzspyinnode);
}
] on (spypoint) in node at (3.25,-1.35);
\end{tikzpicture}
Do someone have an idea?

You can define your own spy style with the example given in Section 49.5 of
PGF/TikZ
manual. Here is one such modification with shadowed spy windows.
