Nice work.

Great work again!

- Look at the pistons closely (everything is in invisible group) and lasers, they are crossing each other but gap between them is just for piston "arm?" so only one laser is active at time
- First version had working valve because it had only one piston, but when i added second with 90° offset, they can act as timing valves for each other, so lasers are near them, but mechanics was working so i wanted them, even as a visual detail
- Add me to google hangouts and i will send you older versions
