You can use an additional form without borders with RichTextBox placed on it. And change form position by timer.

Simple example:

using System;
using System.Drawing;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        Timer timer;
        Form form;
        RichTextBox richTextBox;

        public Form1()
        {
            //InitializeComponent();
            form = new Form
            {
                Size = new Size(50, 20),
                FormBorderStyle = FormBorderStyle.None,
                TopMost = true,
                ShowInTaskbar = false
            };
            richTextBox = new RichTextBox { Parent = form, Dock = DockStyle.Fill };
            timer = new Timer { Interval = 10, Enabled = true };

            timer.Tick += Timer_Tick;
            form.Show();
        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            form.Location = new Point(MousePosition.X + 10, MousePosition.Y - 20);
        }
    }
}
