Pray To Buddha
See these two cherubic priestlings, they are praying to Buddha:
The cassock, prayer beads and wooden fish are three instruments for chanting sutras.

Improved Simple Watercolor Demo
Copyright: http://realtime-watercolor.blogspot.com
As I changed a new graphics card(from Intel 82945G to NVidia 7300 GT), I have the hardware support to the better shading effect.
This time I use the floating-point texture(FP16, in Direct3D, it is D3DFMT_A16B16G16R16F). FP needs not to be clamped, so its precision is higher than fix-point. FP is usually used in GPGPU(such as fluid simulation, soft body dynamics,etc) and HDR.
The higher precise FP format is FP32(in Direct3D, it is D3DFMT_A32B32G32R32F), but it is not supported by hardwares universally, so I use FP16 here. It is adequate for this demo.
Furthermore, I add some paper textures to make it more real. Look at the picture above, the paper texture is papyrus.
Look at the two images as follows. The paper texture is rice paper("Xuan Zhi"). The effect is similar with "Chinese Wash". I think Chinese Wash and Western Watercolor is similar in the essential, while the representation is different.

Why Is Watercolor So Enticing
Watercolor is one of the most popular painting styles in the 
Western, and it is famous for its clarity, brightness and illusion.
Then why is watercolor so enticing? The answer is WATER! Right, it's water.
Water is the headspring of life in the earth. It's glittering and translucent. When pigments mix with water, they will become spiritual too. So the watercolor painter can express some particular mood which other painter cannot. It suits for landscape especially.
Please look at the watercolor painter in the left. It is Yi-He Park in Beijing, China. It is so charming, isn't it?
Can we generate this charming watercolor with the computer? I believe we can! I will devote to this project! HOHO!

[WATERCOLOR]Kwan Yin: Goddess of the Compassion and Mercy
I call this watercolor painter as "The Lighting of Kwan-yin Bodhisattva". The light is very auspicious for our people in the world. As you can see, the watercolor styled painter is charming. It expresses the godlike atmosphere quite felicitously!
I am a devotional Buddhist. I am specially interested in 'Zen'. Let me recommend you a famous website about Buddhism:
The world Buddhist information and education network.
Who Is Kwan-yin?
"Kwan Yin is one of the most universally beloved of deities in the Buddhist tradition. Also known as Kuan Yin, Quan Yin, Quan'Am (Vietnam), Kannon (Japan), and Kanin (Bali), She is the embodiment of compassionate loving kindness. As the Bodhisattva of Compassion, She hears the cries of all beings."
“Remember me when it rains, I am always near. Remember me when you are t
roubled, I will calm your fear. Remember me when you cry, I will always hear.”The detailed story about Kwan-yin is in this website: http://www.crystalinks.com/kwanyin.html

Simple Realtime Fluid Simulation On GPU
Copyright: http://realtime-watercolor.blogspot.com
Realtime fluid simulation is a hot topic of computer graphics. It is also the foundation of computer-generated watercolor. Here I write a simple realtime fluid simulation demo using D3D9+HLSL(using VS1.1 and PS2.0). Following are some screen-shots:
When running, the demo showes one Chinese character 'REN':
Then when you use mouse to drag the Chinese character, it will flow along your mouse's direction as a fluid:
At last, the fluid will be stabled and become
actionless:
If you drag the Chinese character along another direction, then it will flow along different direction:
Ok, that's all! In this demo I use a simplied physical model to simulate the fluid, the effect seems to not bad, hoho, and the performance is well. My video card is Intel(R) 82945G, and it runs quickly in my machine. So the demo is not required the quite new and high-end hardware. Supporting VS1.1 and PS2.0 is OK!

WHAT IS WATERCOLOR?(reshipment)
The original article: http://tfn.net/Watercolor/what.html
Simply put, watercolor is a painting compound using water-soluble pigments that are either transparent or opaque.
Because of the medium itself as well as the paper to which it is applied, watercolor is frequently thought of as a fugitive medium. Not so! While watercolor may not rival oils for durability and longevity, it is a medium that has a very durable and distinguished history and, clearly, a healthy future.
While American artists in the early 19th century seemed to regard watercolor primarily as a sketching tool preparatory to the "finished" work in oil or engraving, English artists of the mid-1700s had already elevated watercolor to a serious medium equal to oil. In England, watercolor was first used by architectural draftsmen and topographers, but soon watercolorists were introducing figures into their compositions. It took the genius of Winslow Homer to reveal to American artists the extraordinary potential of watercolor as a medium of serious expression. Once accepted, watercolor became an inevitable medium for the American painter who, from the beginning, made landscape painting one of the dominant features of the American art tradition. Watercolor's inherent luminosity, combined with its capacity for rapid execution, gave landscape painters an ideal means for recording the fleeting effects of nature.
Some background on the use of watercolor
The history of watercolor is inextricably bound to the history of paper, invented in its present form by the Chinese shortly after 100 AD. Papermaking was introduced to Spain by the conquering Moors in the mid-12th century and spread to Italy 25 years later. One of the earliest paper centers was Fabriano, Italy with mills in operation by 1276.
The forerunner of watercolor painting was buon fresco painting: wall-painting using watercolor paints on wet plaster. The most famous example of buon fresco is, of course, the Sistine Chapel, begun in 1508 and completed in 1514. In Europe, as early as the 15th century, Albrecht Durer (1471-1528) was painting in watercolor. Durer's influence was partly responsible for the first school of watercolor painting in Europe, led by Hans Bol (1534-1593).
The American West was an important area in the history of American art, and of watercolor in particular. Much of the record of exploration of the lands and people west of the Mississippi was kept by artists whose only means of painting was watercolor. George Catlin (1796-1870) was one of the "explorer artists" who used watercolor to document his travels among Indian tribes during the 1830s. Thomas Moran's watercolor sketches of Yellowstone in 1871 so impressed Congress that they voted to make Yellowstone the nation's first National Park.
Great interest in watercolor was created by the reporter/artists of the Civil War. Their on-the-scene drawings of the battlefields were used as illustrations in the newspapers and magazines of the day, the most famous being Harper's Weekly. Links to Famous Watercolorists
