Prezi was really good, it was way better than powerpoint. Im not sure if i'll use it agin but i probably wont reccommend it because it takes a bit to fully understand it. The advantages were that you can make your presentation move around a lot, but you couldnt fully customize backrounds and stuff like that. I would have used different writing colours if i done my presentation again.

We collaberated quite well when usuing gooogle docs, it was really easy to use. Some advantages are you can work on a project with others without having to meet up, some disadvantages is you cant't use animations and you can delete a member from a presentation really easy. I would probably not use it again as there is very little group presentations that we do like that , but i would recomend if the opportunity came. If i done this again next time i would just put some info on the screen and talk most of it.
