Unsanity announces the availability of ShapeShifter 2.4 and Mighty Mouse 1.3, both as Universal Binaries with new features and bug fixes. ShapeShifter (US$20) lets you change the overall appearance of your Mac using “themes,” which includes the look of windows, menus, apps, buttons, and more. Mighty Mouse ($10) allows you to customize your cursors without modifying any system files, on-the-fly. It also allows you to customize all kinds of cursors available in the system — Arrow, I-Beam, Alias, Copy, Move and the Wait cursor.
