For 2013, there is the popular laser show photo calendar of "spectrabeam.de" for the third time in a row. This time double large as in the past. Three copies are given away under all those who comment this post on Santa Claus or send an eMail to kalender@spectrabeam.de !
This year a special thanks to Erich Hans, from which are the majority of the photos.
A complete preview of the twelve pages is on http://www.spectrabeam.de/product_info. ... -A3-German. The calendar is high in the format DIN A3 (2 * DIN A4).
