interval argument of TkTimer can accept a proc object.
The proc is called when decide the interval time for the next call. 
So, the proc must return a milisecond value of integer.

For example,
------------------------------------------------
evloop = Thread.new{Tk.mainloop}
ary = [500, 1000, 2000, 4000]
TkTimer.new(proc{tm = ary.shift; ary.push(tm); tm}, -1){puts :hoge}.start
evloop.join; exit
------------------------------------------------
