It is quite easy to get an effect like a net by using several mirrors and thus reflecting the beams. If you use 3 laser projectors together with some mirrors, it's rather easy to generate a great effect!
We suggest to use only very precise laser systems for doing things like that, e.g. the Pure Micro Series, the Purelight Series or the PIKO / NANO products. We suggest to use the BEAM-10 reflection mirrors.
