I just happened across this gem: Elizabeth's note to the Easter Bunny last year. We were staying in a hotel. I gather than 907 was our room number. (She was 5 then.)

Who Among You are Geek Enough to Decorate Your Easter Eggs in Mathematica?tag:typepad.com,2003:post-467385682008-03-07T19:30:30-05:002009-02-05T18:19:13-05:00I dare you.

<div xmlns="http://www.w3.org/1999/xhtml"><p>I dare you. Send your Mathematica egg notebooks to <a href="mailto:kathryn.cramer@gmail.com">me</a>. This activity, begun last night and avidly pursued this morning, has proved wildly popular with my children who are threatening to run me out of toner in my color printer.</p>
<p>Here's mine:</p>

<p>Now show me yours!</p>
<p>UPDATE: Michael Croucher at <a href="http://www.walkingrandomly.com/">Walking Randomly</a> has risen to the challenge and <a href="http://www.walkingrandomly.com/?p=79">put me in an egg</a>. There will be a number of other Mathematica-generated eggs available via the <a href="http://demonstrations.wolfram.com/">Wolfram Demonstrations Project</a> next week (URLs TBA) including three fancy ones by my dad, <a href="http://faculty.washington.edu/jcramer/">John Cramer</a>. There have also been forays by users of <a href="http://www.mapleprimes.com/blog/jpmay/colouringeastereggsplots">Maple</a> and Sage. Also, see <a href="http://www.flickr.com/photos/pugno_muliebriter/450952660/">some real math on real eggs</a>. </p>
<p>URL UPDATE, 3/17/08: Michael Trott, whose book inspired my son to ask for Mathematica-generated patterns on eggs, has made an egg notebook of his own and added it to his<a href="http://www.mathematicaguidebooks.org/"> <em>Mathematica Guidebook </em>website</a>. He's made a very elaborate notebook which will be expanded and included in the Version 6 edition of the <em>Mathematica Guidebook for Graphics</em> volume. </p>
<p>(Those without Mathematica can view and play with these egg notebooks using the <a href="http://www.wolfram.com/products/player/download.cgi">freely downloadable Mathematica Player.</a>)</p>

<p>Also, there are now a number of <a href="http://demonstrations.wolfram.com/search.html?query=eggs&imageField.x=0&imageField.y=0&limit=20">egg notebooks on the Wolfram Demonstrations site</a>, with more on the way in the next couple of days.</p>

Peter asks an important question while I'm cooking dinner here. He wants to write a letter to the Easter Bunny and he wants to know where the Easter Bunny lives. Does anyone know?
