Is there any chart that shows the rise and falls of the LTC Value over the past weeks? Perhaps even compared to the BTC value?
There are some altcoin charts at
https://vircurex.com/ (LTC, DVC, PPC and others), although they represent only the value at the Vircurex exchange.
Edit: Ah, and there ist
http://btc-e.com too, but the charts there are for a few days.
