I am no great web designer, and hardly had much previous exerience with XHTML/CSS and web UI designing. So, as many of you must have noticed that the old UI of kreeti.com, was very simplistic and minimal.
Then I discovered, this nifty cube page, and it has completely changed the way, the site looks now. There are no more sharp corners, the pages are more colourful and have much improved look even in IE. Nifty cube is a wonderful tool.
