Having just come back from a motivating VSO RV (Returned Volunteer) weekend, I've finally got round to starting a website where I will be gradually adding videos, photos, sounds, educational ideas etc over the next few months.
At time of writing, there are already a couple of videos, and my complete "Virtual Gilgel Beles" where you can "walk" around the whole village.
Check out the site at: http://www.aboutethiopia.co.uk/
I also plan to visit as many schools and groups as I can to spread my experience. Email me if you are interested. Contact details on the site.
