My first Mantis !
Most probably Mantis religiosa, the Praying Mantis.

Green caterpillar, probably the larva of a sphinx moth.

Summer sunrise on the shores of the Ionian Sea. 

More or less corresponding to the 2nd Google+ anniversary, I am happy to announce the launching of CDA Photo Google Page !!! (Some) brand new albums, news and technical posts or whatever the wind will bring !

Basically, just buy this sound sensor, stick it to an Arduino and with this cable trigger the flash (I did it through an optocoupler). Have fun !
