While I'm waiting for the postman to deliver my G9000-3V Mudman (from HB Watches) I decided to have a little fun with my great DW6600 (still one of the best designs by Casio, IMO). In case you don't remember the DW6600, here it is (mine is 7 years old - I wear it every day):
I placed my camera on a tripod in my garden at night - and started writing letters with the Illuminator. Exposure time on the camera was 3 seconds. I put the different letters together with Photoshop and this is the result (click to enlarge):
If you zoom in on the picture, you can see the DW6600 display at the end of some of the letters.
