I couldn't find this mentioned in any of the forums here, but one of the bogleheads has created site, www.portfoliocharts.com
He uses data from Simba's spreadsheet, available on bogleheads and provides a bunch of tools. He has results from most of the well-known lazy portfolios. You can also create your own portfolio in the calculators section. My favorite two calculators are the heat map and start date sensitivity, which is an interesting way to look at volatility over time.
Definitely fun to play with - and as always "past performance may not be indicative of future performance"
