Having been to BETT and seen the new Elmo L-1ex Visualiser, with a remote control feature, I discovered that new software has been released for capturing and editing pictures and video. It also allows time-lapse photography. The download is free (27Mb) and you will need to uninstall the original software that came with the L-1N first.
Get it here from the US website where it goes by the American model name of TT-02-RX, rather than L-1ex http://www.elmousa.com/download-archive.php scroll down to Document Cameras - Digital and look for the Windows flag to download the zip file. Then unzip the setup program to install it. (Mac users download the Mac file instead)
For those who found the original Elmo software old fashioned, I found the new version is much smoother and easier to use, and the time-lapse great for science if you set the settings to .avi, and choose a suitable interval between photos.
