2.5D aka Isometric Pixel Art

Wanted to do a pixel art theme on my website, and ended up reminiscing too much on Roller Coaster Tycoon's retro style (good lord...) and found lots of goods in the web, including this awesome library obelisk.js. This library elevates the view angle at 22.6 degree. I have forgotten all engineering drawing days we spent on Solidwork, and this word Isometric View reminded me fully of the 4 years...

Since US Open 2020 is around the corner, a tennis court is all we need.
