One is Beam Effects show the laser beam that progressing in the air to the audience, the other is Screen Effects show the laser graphics on the screen that drawn in moving a laser spot on the screen. The first one is used better than second. The beam effect is very exciting, so that many Laser Light Shows are also being given.

This shaking makes the letters shimmer with a moire brilliance that mimics a computer screen. The text comes from the artists’s local deli’s ATM machine. See also the Scrollbars by Jan Robert Leegte.

MAKE pal Alan shares his experiences from our first volume- I just finished building my $14 video stabilizer as seen in Make: Magazine, and I must say I am amazed with it. It has produced a nice, smooth pan in every test I have performed so far, and it seems sturdy enough that I can let it support my digital video camera without becoming too nervous 
Handy. This is a little how-to guide on crimping connectors for various electronics projects. The art of crimping is sometimes a difficult one, but necessary for 1) reliable and 2) decent looking connections. Breadboards are nice for quick wiring projects but in the long run they are unreliable and look pretty nasty.
