Re: Getting a hook from shell mode to do motion detection?

Interesting, I hadn't thought about Java, but I'm on a Raspberry Pi so
the ARM chip might be reasonably fast at it.

I tried it on the S70 and it looks like at some outer level it detects
it, then says it can't initialize.  I tried it on my Nikon D5200 but
I'm having trouble with my Nikon cable and it didn't work at all.

Nice idea making the mask as characters, I wasn't sure how I was going
to handle that.  I'm still stuck in double pointer hell but I haven't
worked on it in a few days.
