Virtual Estate

My life usually goes through changes, beyond the cadence of the semesters and summers that professors see, or the cyclic rhythms of conferences that researchers calculate out; my changes include abrupt travels, new pastime (mountain biking now), unruly working hours, evolving research topics, or obsessions with new thoughts and gadgets. So, at some core level, I appreciate a non-changing, focus point of a piece of real estate that is mine, my home. For amusement, here are two such permanent pieces of estates, these are virtual.

• You could buy a decimal digit of \pi at mysliceofpi at its face value of dollar (digit i costs i dollars, and its font size is a subtly increasing function of i). You can rent out or sell the digits too. The page will remain for a "long" time.
  
• Oldie: You could have bought a rectangular set of pixels at a dollar a pixel (1000 X 1000, you do the math) at million dollar homepage, and the seller gurantees "The pixels you buy will be displayed on the homepage permanently.", You can put a logo and link it to whatever.
