Anyone else seen this? It's like Guitar Hero/RockBand but it uses your own guitar and actually teaches you the songs. Only downside is you have to have an Ultimate Guitar account to use it, and I created one solely for this - if you already have one, you probably have already seen this.

I've only just started using it but it looks pretty nifty and you get two free downloads with it. (Songs usually cost $0.99 per, so probably about £0.59/£0.69 for me).

I can't for the life of me follow the little descending dots, so I stick it on tablature mode which scrolls with the songs.
