Do you write Java ME applications? Want to display the results of your work to visitors like that fancy emulator that comes with Mobile.Processing. Well, Michael Powers (developer of the great MPowerplayer MIDP 2.0 SDK for OS X) has developed a free web emulator you can use in your site. Here’s how in three easy steps:

Bam! You’re done.
