My PHd supervisor showed me this the other day when I mentioned I was giving a presentation on my work to the other research students. This isn't a big thing but I needed a means of displaying slides, I was going to write my own system - I am not a great fan of existing packages, I dont have the funds to get OfficeX and it seemed the easiest solution.
Anyway, I put it to one side [by that I mean I book marked it, and left it and forgot]. But I am very impressed with the article and I am definatly going to go play with it. Just need to get TeX and friends installed again on my iBook to play.
Thanks for a good article!
