Create your own Rainworks street art

Remember the street art that only shows up when it rains? Rainworks is a message or image on sidewalks all over Seattle that stays hidden when dry and only shows up with the surface is wet.

It is done using a superhydrophobic coating which makes surfaces repel water. Pretty cool stuff.

And here’s the interesting part. The creator of Rainworks is now on Kickstarter to seek funding to manufacture the Rainworks Invisible Spray. Yes. You can now create your own Rainworks in your own city.

The spray is eco-friendly and biodegradable and generally last 2-4 months. You can even remove it with cleaning product and a little bit of scrubbing.


To get the Rainworks Invisible Spray, simply pledge US$25 or more on Kickstarter.


Look forward to seeing your street art on the Rainworks map.

Canon EF35mm f/1.4L II USM

Canon just announced the successor to their popular EF35mm f/1.4L USM which was release in 1998.

Slant with cap

The Canon EF35mm f/1.4L II USM is the first model to use Blue Spectrum Refractive optics (BR optics), an optical element capable of achieving a new level of sharpness by reducing chromatic aberration when combined with concave and convex lenses. This enables the lens to render superb image quality and performance, making full use of the brightness of a large aperture.

BR optics is capable of correcting chromatic aberration, thus significantly reducing colour fringing, a common occurrence found in large-diameter lenses. In addition to BR optics, the lens is made up of two aspherical lenses and a UD lens, which helps it achieve high image quality across the entire image frame from edge-to-edge.

The newly designed 9-blade circular aperture is able to produce more attractive bokeh effects. 35mm is a great focal length for both Full Frame and APS-C cropped frame.

The new EF 35mm f/1.4L II USM is expected to be available in Singapore from mid-October 2015. Singapore pricing is not available yet.
