最近似乎流行用 GPS 接收器轨迹作画，号称是把地球当画布，GPS 当画笔，气势何等磅礴。不过，行为艺术其本质就是闲得蛋疼，那个号称画了世界上最大的简笔画的家伙最后自曝是假的。另两个相关的站点：The world is my canvas，复活节大兔子。

这个想法还是蛮有趣的。不过我没有那么吃饱了撑的，我直接爬到实验室楼顶去试画了一张跪拜康神图，耗时不到六分钟，然后把 GPS tracklog 导出即可。下面有绘画过程，GPS tracklog 可下载，童叟无欺，如假包换。

GPS tracklog 每秒一个数据点，下面这张 GIF 我设置的是 25 fps，也就是说比我实际速度快 25 倍，不到 14 秒就应该完成绘画，但是似乎有些弱的浏览器不能这么快的放 GIF……据观察，Firefox 表现良好。

interesting. what gps receiver do you use? it seems to be quite accurate.

Comment by ji — June 6, 2008 4:37 am GMT-0700 #
It’s a very old GPS receiver but has WAAS enabled so the (absolute) accuracy goes down to about 3 meters; and also since I did this in less than 6 minutes, the relative accuracy is even better than that.
