Want to see the previous version/look of your site/blog in its original form? The previous version means the color graphics, templates, flash contents and all the so called things before you changed it to new form. Google have the answer. They stores your site/blog in their servers. They are called cached pages in Google.
You can find the cached page and cached time of your page by searching your page in Google. Just search your site in Google, below your site result there is a green arrow pointing downwards and just click on that and you will find 'cached' link and click on that link.
Now you will be directed to your old page which the Google was cached.
